I didn't make these clear before, I guess.
Usernames:
Your usernames should be the name of your RPG character. For example, my character's name is "Ayaami" and that is also my username. Usernames should not be things like a screenname you would use on a chatroom like "HorseLuver123" or something random like that.
Avatars:
You have to have an avatar before your profile is approved. The avatar should match the description of your character posted in your bio so that no one gets confused.
