Can I ask who decides the map rotation on the Retro server? The current rotation has completely drove the server into the ground. During prime time, you can't find more than eight people on the server on most occasions. If I had a recommendation, it would be to set it to Dust2/Cbble until you get some kind of audience...those are the only maps that retain people.
Also, I would highly recommend removing stats from the server. As far as registration goes, GC is one of the worst and I'm only one of many to think that.
