Rules:
1. You may only claim 3 separate characters at a time. If you want another, then drop one of the ones you have and pick up the one you want if available.
2. If another person has a character you want, you may trade characters if the other person wants to unless you don't have the limit number of claims and they don't want the character anymore.
3. There isn't a NEED to RP as the claimed characters, but take note that some people may want to RP as or with that character.
