This is the official map list:
de_dust2
de_inferno
de_dust
de_nuke32
de_train32
de_westwood
cs_assault_1337
de_dust2002
I would suggest removal of, train32, westwood, assault, de_dedust2002 and de_dust.. Although I like some here a lot of people don't.
We should have dust2, inferno, nuke32, kabul and aztec
