I would like to change my characters name, how can I do that?
Aw 
there was a two week (?) period after the merge that allowed you to change your name for 1 TP (basically 5 free name changes with your daily free TP). I don’t think that’s possible anymore, so you’ll probably be charged the full cost now.
Anyway to change your name, just press F1 then use the little pencil next to your character’s name.
