MUME will move to a new machine in the next very small (1 or 2) number of days. Its new IP address will be 193.134.218.98 but nothing else should hopefully change. The DNS entry (mume.org) will be moved at some point, but I'm not sure exactly when. Jot down the IP address somewhere if you want to continue playing until then. The game will be closed for a while during the migration. I don't know when. Sorry for the short notice. - Dáin
