I would say leave the vote. Nothing wrong with voting. Not giving a chance to vote for the next map is pretty old-school.

Zat, the thing is that compound is liked. Yesterday we had a classic KM day:
1) de_aztec , people start joining
2) shitaly, twice in a row due to shit vote options.
3) de_dust2. Twice because people love it.
4) cs_compound. Once, not too bad.
5) cs_militia. 30 minutes of misery.
6) de_cbble, because people love it.
7) de_contra = every one gets kicked.
Hopefully, by putting correct fixed versions of maps and removing shite no-one likes, we can spice this routine up a little bit.
I would stick with aim_ak-colt. No awps and its pretty neat. I wouldn't mind the awps, guys, I would probably love the awps because I try and train my awping as much as possible now. With all respect to good awpers on our servers (I do respect you loads), your skill is far beyond anything an average KM player can handle. On an awp map, or, on an aim map with awp available... The score board will look like this:
60 Frags, 5 Deaths Zat, Comm, LiKE, k4nt <stick hax0r name here>
35 Frags, 11 Deaths <next decent player>
18 Frags, 25 Deaths <everyone else>

So we will leave out awp maps for a moment. Compound stays, Jailbreak is now included.
Regarding, fire/contra/strike... Anyone has any recommendations? Zat, you say contra is dull... I can replace that with...
