I love to MUD too, but the community is getting smaller and smaller... All moving to MMORPGS like WoW, KO, RO and FFO... All the good times.. MUD servers go down too due to low P-base...
I also enjoy good ASCII games like DasMarklar said. My personal favourite is <a href="http://www.adom.de" target="_blank">Adom</a> but alas, it too seems to be dead too... Guess the world is moving on... Its sad.
