Try the Mia survival map pack on Moddb.com - it should be downloadable.
Well, about the Community: I wish there would be some more players (at least there came some new ones last weeks^^).
So Raj's right when he says we got enough, but on the other hand I think it's sad to see just one only working 24/7 server.
So my Idea was running a 2nd server Friday night when Raj's server is full (happens not every week, but sometimes).
