Voting really cannot work with the way TF2 is setup now with mani; after 3-4 seconds, the voting window goes away (its a glitch with the TF2 code, NOT mani), so we are better off using a (GOOD) rotation. I think we have good maps listed (heck, I chose them!) but I think we need to work on a better order for the rotation.
Another issue we have to address is the problem the server has where after every steam update, mani and hlstats break and the rotation breaks. Basically our server gets put back to default settings, which are less than optimal. There may be ways to fix this (google), I read somewhere about making files read only for example to try and combat them from being overridden.
What I am saying is before we even implement some of the changes kappa suggested, we need to make our server stable and user friendly to play on, then we can worry about stuff like forced melee, WCU logos, etc.
