In some worlds though, you can be you if you'd want. The one with the quests I played it but chatted as myself. The Hogwarts one I acted like two other people (I had two accounts) and the chatroom I was someone else but you could just as easily be yourself. Those are harder because you'd have to actually type your actions *she said as she tossed back her hair, her mouth breaking back in a wide grin*
The one with the quests you could type *laugh and it would put *PurpuraLipstick laughs* in for you.
I think I know way to much about this stuff... I'm a geek.
