in the multiplayer I notice on the waiting list that people have red and blue names but mine is green why

It mean it's you. ;) Other people see you as blue, unless your the operator of the room, then they see you as green as well with an @ sign.

Red at the top means there the one who is first in the playing list.

Yellow/red names with %/~ signs are game masters.

The Msquad members might be getting a $ next to their name ingame soon. Anyway, closed since this solved the problem.
