Puzzling as I have been alerted that my sub-class has External Links it does have links but they are internal to this site the cleric page, cleric spell page and the rouge class page. like all the sites pages they have internal links why am I bared from using them?

too similar to _________ clicked the link got an error I do not want to release my work to any one to use print and make profit. I want it to use. 

I want to use what I make in my own campaign not have some one piggy back my work to sell subscriptions. 

which is it no one can see it not even some one in my campaign?  am I just wasting my time and effort. I get the whole you have to buy the ebooks to see stuff and use most all this site and hard covers do not count and proof of purchase. but this you can't crap? The share limitation of this site is overwhelming and the more time I am on this site trying to do things the more the 500 dollar bundle and monthly subscription are pretty much mandatory. And yes I can use the basic blah blah blah for free. question is do I spend time on this site making the spells for my sub-class in the home brew or is that another colossal waste of time?

 This Subclass cannot be shared with the community for the following reasons:

Remember, private homebrew is automatically shared with other users in your campaigns and does not need to be shared with the community for players to access.

To be honest I had a problem to understand what is actually wrong in your case. There are several things you can check. 

1. All your homebrew can be shared with your players in the same campaign without being public - make sure you click "allow sharing content" in the campaign view. 
2. You cannot publish (for everyone, not your friends only) homebrew if you used something from outside the SRD (http://dnd.wizards.com/articles/features/systems-reference-document-srd) 
3. In order to share materials with your players in the campaign, they have to be in the campaign and you need to have the Dm subscription (https://www.dndbeyond.com/subscriptions). 

If none of this works, please try to be more precise what you want to do and I will try to help you out. 

Links I linked it to rouge, cleric classes and cleric spells not using those classes just a link to another window if some one would wish to look at those classes or class spells. I had intended to make my own spells for the class. I deleted the links and the only thing that's left "is the too similar to _________ " which I can not look at. I had links to my sub-race Dúr egla (Dark Forsaken)  a sub-race of drow. the sub-class was/is a assassin/priestess class of female Dúr egla but I guess is was to close to someone elses assassin/priestess drow female only class that I can't see. wasted 4 hours fumbling through making that an researchin only to click and be denied. good thing I found this out before making all the spells. Not sure how much money I would have to dump in to this to find out 55 bucks a year to DM and use this site, 30 bucks for the DM ebook, 30 bucks for the monsters ebook, 30 for the ehandbook thats 115+ bucks.. oh well I can see the class and I can take what I build and hard cover it my campaign well just be off line.

Thank you for helping I was kind of (by "kind of" I mean really not happy in the ugliest of ways) I'll just find inspiration in Gary Gygax and J.R.R. Tolkien I'll make my own there is no "you can't do that" in my world LOL

Some spells, classes, and etc that are in the Players Handbook are still not visible here without paying for them. So even if the spell is from the PHB, it might not be linkable if you want to publicly publish. I just ran into that myself with a new Warlock patron--had selected the Patron Spell List spells, and it turns out two of them (from the PHB--Phantasmal Force was one of them) were part of the 'Digital Content Pack' and not free content.

So I just removed those links, included the spell names in the plain text description, and I could publish. A bit of a hassle, but not a big deal in the end. If the person wanting to use that patron has the PHB, they can look the spell up like usual.

But, as Nathirwalowsku mentioned, if you just want to share your homebrew with people in your own campaign, then this won't matter. Create it as you want, save it, and make sure you have sharing setup, and you're good. It'll still say "OMG you can't publish!", but you can just ignore that, and your players will be able to see it. 

I keep running in to barriers here I did not want to make a sub class but was forced to get past the first hurtle. LOL this all started when I seen drunk on home brew on my facebook. signed on here for the most part to clinch the XXSUPERHEROXX name I been using that name for over 30 years. anyways I am stoked and all fired up to do things I dug out my e1 tomes and modules spent 1000's of dollars 39 years ago and have a crap load of content.

the work around some 15 years or so I was Racing a widow maker dirt bike and made a message board spent 1000's of hours hacking and programming. I had links to tracks races accessories a lot of content on that then vision free turned off their servers I lost it all. a mouth or two ago I made another for a private place of my own on the web no members as of yet don't even know if any one can find it googling my name well get you a lot of pages to search LOL. So I just made another Category and board to work on  this way I can make stuff and it does not have to be a sub-race or sub-class cut and paste works not like this site where I have to use the ctrl+v pain in the back side thing. sense I am making my own race, classes and spells I don't see a conflict with Hasbro as long as I am not making money with it. plus no restrictions on adult content it's a win win. 

short of inspiration this site it useless tell I pay the message board is out standing as I have been an owner of one for years! I been a little irritated when I posted but the people that responded were top notch unlike the WOW people on that forum.

anyway I have plans with in plans<(Dune reference) =P sorry I can't peruse your created content. 

I honestly have no idea what you're on about. 

You can use your homebrew and share it with your campaign regardless of whether it is published or if anyone has a subscription. "Remember, private homebrew is automatically shared with other users in your campaigns and does not need to be shared with the community for players to access" says as much.

The "is too similar too ___" message sometimes appears when you leave description fields blank.

Try DMing a mod and have them take a look at it.

Holy crap some where in my googling and research I picked up a nasty and had some rather trying issues with my browser and this site I think I fixed it the sites not opening windows so sorry about not responding right away. I have yet to subscribe to any thing on the site as of yet do DMing any one is in hold tell I can figure out basic stuff like how to play again the games gone through 8 generations. I thought e1 was daunting  with share mounds of data running through the sub-class making just brings about deed. 

So I thought I would at the very least use my made content on my toon's, I did switch over the female drow to my sub-race but when I went to switch to my sub class is would not show me the class so thinking no one but me can see the subclass as it is not done but a work in progress with the block it's to alike to another sub-class. still working on it thought multi class would fix that but I need to learn a few things to finish that it appears. 

any way thanks you for responding and trying to help. 

"Gurth is currently too similar to Circle of Spores to share with the community." circle of spores from what I looked up in not on home brew. their a druid sub-class. Gurth is a female only sub-class assassin/cleric mix from a drow sub-race of a matrilineal society system. if someone knows of some basic tutorials I would like to read up on what I am doing wrong.

The "is too similar too ___" message sometimes appears when you leave description fields blank.

Give it a description.

having problems working the blockquote thing but this is the short description

"The Gurth are a sub-class of assassin/cleric and fall under the class of assassin with cleric spell abilities . The Gurth class is only found in the Dúr egla race and the Gurth class is restricted to females only. The Gurth are extremist their unwavering devotion selfless service to their Demon Goddess Queen Lilith make them the most feared of the Dúr egla. The Dúr egla people call them Gurth (Death) they are sadistically cruel and derive pleasure in torturing and killing. Domineering they loth everyone having no mercy or empathy they are feared by their own people. Being favored by the Demon Spider Goddess they are blessed. The Gurth are schooled in the making and use of poisons and the darkest of the dark arts using both to further their Goddess will. "

main description

"Gurth are Lilith's assassin priestess skilled in domination, seduction, deception and torture. As Lilith's priestess they have dark art magic of their own though similar to cleric spells but far more sinister and do not fall under a cleric class. They can heal but the cure might be worse and more painful then the illness. Listed under rouge as a sub-class they are not thieves out for plunder or riches. They well take assassination contracts for profit to raise capital to further their Goddess will but once paid for services they well most likely assassinate the person who hired them taking great pleasure and time in doing so.  They well resort to common thief and murder to survive."

I have yet to finish this as I am working on the Dúr egla race specs on my forum but think of "the sword of truth" Mord-Sith. but way worse.

I was looking around googling stuff found a guy on you tube who was winging it calling it an tutorial for making a sub-class he made it in word so he bypassed a lot of hurtles this site has. basically did the same only using a private area on my message board.

When I got to spells so I weeded through the home brew and started making cantrips and spells and an odd thing happen in the spot that asked who could use it I typed Gurth and it gave me a fill "rouge gurth" sweet! I made some wicked spells the only one that flagged was cure wounds which it is but mine hurts a lot more then the wound and heals disformed and well hurt for the rest of their lives. so my Gurth can cause agenizing wounds with it and heal them excruciatingly painfully and disformed! I called it Gurth gift. =P made a gurth enslave spell, gurth Lilith that makes the cast appear as Lilith with Liliths 23 charisma bonus with drow poison as the material component applied to her lips seduction with a kiss of death! awesome!

I don't know if I well ever get to use any of this on here but damn I am having fun and learning as I go! dinky dinky do fun for me and you! zoom zoom time to make havoc dig in to my bag of mayhem and unleash anarchy upon the world.

"For the Horde!"
