No, you set up your log in then you set up a "display" name that shows in game and in the forums.
If your not sure what you set yours up as, go into the chat box and type in any old thing you want and hit enter. It will show you your name in the chat box.
I put in a request to have someone make a Champions Online vent channel. I don't have admin on it or I would (sorta handed all that stuff to others some time ago).
The vent address is oxygen.typefrag.com and port is 28911
The friends list is borked all the hell, so vent would be a good way to see who's online even if you don't have a bloody mike, bloody... It starting to get tougher at the higher levels so team work is going to be required.
