In my experience, and being brutally honest, only 3 maps give an overall increase on the number of players on the server: de_dust2, de_inferno and de_dust (believe it or not lol) sometimes de_westwood does too, but not always.
Personally I'd get bored if I only played those maps but then this isnt about oppinions this is about keeping the server healthy. I suggest we remove de_train32, cs_assault1337 and de_nuke (I love that map

) and make a judgement call on de_dust and de_westwood. Gimme your thoughts folks - presonally I love italy, nuke, office and aztec but if it's not good for the server its not gonna be a realistic proposition.
I always felt that we should have other maps on the server, in the maps folder, but not part of the maplist so an admin can change to them or make a vote for them but they wont come on if no admin is about.
Oh and the recent lags on the dedi box didn't help at all but I assume thats all fixed now?
