I agree that the current respawn times are too long. 10 seconds would be good I think, but it is aggravating to sit and watch for 20 seconds each time you die.
I have been on call and working a goofy shift this week, so I haven't been on in a while, but starting the weekend I'll be around more again.
As for maps, the game is still fairly new so people aren't sick of the maps yet (dust anyone?), but if people find new ones they really like, we could at least get them on the server, but not in the rotation yet, so if an admin sees its a good crowd, and people want to try them they can.
