There is a steam group.
But where is this steam group?
It's just for the server admins themselves.
It might be a nice idea, but then again, lots of us come on under pseudonyms to catch out the trolls.
I can see how it might help, particularly if the steam names were listed alongside those who want to be able to be contacted. It could potentially result in faster responses to incidents in the servers, and I don't really see any downside, so long as someone is willing to put in the effort...
