i seem to have signed up to steam years ago (i'm talking when ET was new, lol) but i, apparently, joined a clan how can i get rid of the [dcw] in front of my name?
It should be under options where you can change your name.
Hello Evil
If you're talking about your in-game name then you can change it through options (just launch the game)
otherwise, I haven't got a clue what you mean
rightclick on the icon down right corner of your screen (taskbar) -> settings -> change nickname
If you mean the Steam name then.....
Open Steam Friends
Go to View>>Settings
It's there at the top.
Otherwise as Blunt said
