Yeah I have been playing at this one MUD now, called the Realm of Magic, for a while now, and it is really awesome. You can do just about anything, they have 8 different races and 5 main classes, as well as subraces like vampires and werewolves. Its based on D&D, mainly, and therefore you have a lot of options to customize and roleplay. If anyone is interested come check it out!
For those who don't know, a MUD is a text-based MMORPG that has a lot more options for customization of a character than graphic MMOs due to the difference in difficulty between coding for graphics and coding just text. Even though it may sound lame, (I mean, come on, no pictures!) but really it is loads of fun.
Its called Realm of Magic, and you can get to it at rom.mud.de
