A good friend and myself worked for a while on building up a MUCK, running Fuzzball 6.0.
Unfortunately, we were a little late to the party, and it proved difficult to find good actively-maintained online resources. To that end, I created this list of active MUCK-related sites, as of September 15th, 2011. The links were last verified on November 11, 2015.
I hope it serves someone well.
Update 2015-11-11 - Since it's been 4 years since I first wrote this list, I should mention that I actually wound up becoming frustrated with the limitations of the MUCK software, and abandoned it for the much better-documented LambdaMOO, before utimately losing interest in the whole endeavour.
