Fonze,
I don't think anything has happened to this server. Sometimes, there are just fluctuations in the numbers of people that decide to play in particular servers. Either way, it is April now. Many of our members are in college and finals are nearing/looming for us in the next few weeks. Obviously, grades are of a higher importance than some video game to most people. This is probably the prime culprit of fewer people being in there. I will try to make a conscious effort to help out whenever possible to change this.
I'm guessing whatever you think has "happened" is merely temporary until Mid May-June roles around.
