I notice quite a few people use different display names for forums, Mumble and/or in-game, which leads to a bit of confusion. I realize the nature of the game does not always allow people to use the names they want in all places, and that's fine. But could we at least try to make sure that it's possible to see who is who somehow?

Forums: if your forum name is different from your in-game name, write your in-game name in your forum signature.
Mumble: if you use Mumble for other things than just PS2 and use a different name there, maybe include your PS2 name somehow, like in parantheses? (Jesus_Phish(Tuimic) is one good example of this)
