The Nirvana tabs I mentioned are all listed individually there, though. I haven't submitted the compiled Nevermind collection. I'm saving it for after I've done all of Bleach, Incesticide and In Utero, then I'm going to combine all four into one massive omnibus.
Incidentally, I don't use tabs myself anymore. I can pretty much figure out most stuff on my own just by ear. But I like writing tabs. It's become a hobby. Plus it helps other folks learn, so I get a kick out of that, too.
