Once you choose a character, that will be your character if you are accepted. You CANNOT change your character once it has been assigned, so choose wisely.
We, at this time are accepting CANON characters only, no made up characters. You have to chose from who's available on the list, NO ACCEPTIONS. The few non-canon that I have allowed here are made by people who I have been roleplaying with closely for over a year.
If for some reason you do not get accepted, myself or Prongs will send you a PM and explain why. You may attempt to correct the problem, so don't give up.
