Well aside from having to wait a while(our own room is like that : ) ) you may have the setting listed set for private room.
// Offline mode ( This when set to 1 will make your room not appear on a WinMX listing )
Offline=0
So set that for 0 if it is not already, save the config file and reboot server , I hope that its as simple as this but please let us know if you need more help.
