MUDs are a class of games played on the net. Mud is an acronym for (M)ulti (U)ser (D)ungeon/dimension/etc.. everyonce has their own revision of what the D stands for, so make a choice and use it. Since I have my own mud, so I've opinions galore on the subject of what they should be and shouldn't be. I'll wont bother to share them with you, If you want to know.. visit my mud and over time you will get an idea of what they are. It would take too long to articulate them here. I have some information I have put together over time, and I'm putting them here.
