I don't really see what's so disgusting about mudcrabs. As a matter of fact, I find them to be fairly adorable.
-puts Serious Face on-
I've been here a fair number of years (lurking, under your bed, stealing your slippers). Just never got around to making an account until I made a few edits "anonymously" under an old IP, and decided I didn't like doing that very much. A little hard to keep track of a talk page (for more than a week) without a freaking watchlist, unless you can remember everything you've done, EVER.
As far as editing goes, well...I do a little of this and a little of that. I don't really go out of my way to patrol or anything, so it's mainly spur of the moment or the "I've got a a fever, and the only prescription is improving this page"-style edits (no matter how trivial-or drastic-the improvement is).
