Forgo Character Sheets, do applications via 'Introduction Post', so to apply, you have to create what would be your character's first post. Obviously, the GM IC launch will have to be live at the time of applying, but this would alleviate the first post dilemma where if you can't come up with a first post, you simply can't apply. Character sheets are easy to write; posts are a bit harder. You would be free to deviate or expand upon your first post so long as you do so within the applicable window. If at the end of the window, you have not posted the 'post' that you submitted for application, you either have to post it or withdraw.
