Editable Character Sheets
It seems like I can't edit my character after submitting or after approval, the latter of course making more sense. So it is possible to allow for that? Even if it just sets up another submission, it would be nice to fix or elaborate.

You can now edit your character after the start of a game! Just go to your character’s page (by clicking on them in the “Cast” list and click the “Edit” button. This will allow you to edit your character’s name, description, and avatar image.
Note that this is intended for fixing mistakes or fleshing out your character. Don’t use it to change who you character is, fundamentally; that’s something that should happen in the course of storytelling!
