I'm trying to add a homebrew creation to the main page, but it is "Too similar" to "Circle of Spores".  There isn't even a "Circle of Spores" in the page thing.

Okay, first of all there is no “main page thing” so I’m not really sure what you are talking about.

Second of all, Circle of Spores is a Druid Subclass.

It seems like you want to share/publish a homebrew that you just created. Is that correct? If so, try re-saving the entire Homebrew, the system only picks up those compliances when you do that.

PS- If you just finished writing your homebrew then I recommend not publishing it right away. Take some time, maybe a couple of months, and fully playtest and edit your homebrew before publishing it. Once you publish it you won’t be able to edit it any more without using eplacing it with a new version. Remember, you don’t need to share/publish your homebrews just to use them.

Ohh, thanks for the advice!  Is it possible to take down stuff I've submitted?

 Nope. Published is permanent.
