Right now, I have two complaints:

[list]
[*]People who take their time to comment and complain -- without doing their research or even fully understanding the situation.
[*]People who keep pinging you, nudging you or bothering you to start IC or respond [i][b]AS SOON AS POSSIBLE!![/b][/i]
[/list]

That's about it for right now, otherwise, I'm happy as a bee when it comes to Roleplaying!
