If you are in a role playing forum or guild:
1) You make your character

2) You make a bio about him/her

3) You give them powers if it ask if he/she has power pets, weapons ect.

4) You talk in 3rd person (you put your characters name) or 1st person (if you talk in 1st person then you post your pic of your person)

5) You don't just make a profile then not do anything, if you make a profile the other people in the guild/forum might expect you to participate in the chat

6) You make stuff up to go along with what the person before has posted
