I have gone through and did what I could to create my subclass and when I look at it in my collection I see the following message.

• This homebrew Subclass does not have the necessary class features with the correct required levels.
   

I only have the one in there so far called the Swordmage. I am not sure what I have done wrong or missed in my creation.

You do not have to share your creation to use it in your campaign.

That said, check the changelog page for automated checks that cause this message to pop up that prevents you from sharing it.

Going to close this out, I think I found my problem. I was trying to create a full call as a subclass. Going to rework my idea into a subclass and try it again.
