The forums have alot of boards to post in... to an extent.
Theres a few topics I'd like to make, but no board to post them in. So maybe you should make a few more boards, like off-topic boards, server status boards, so noone floods your hamachi with "ofmg iz srver dwn or crshed or iz smthn rong wth my pc111oneone@!!!!oneone". It could also bring more players to the forums, and give players something to do when the server is down. It may even keep some of the people registered to the forums more active. Maybe make a poll on the boards the players want.
