You're supposed to be able to edit your monobook somehow and then you can look at someone's contribution list and ask for a count.
It seems like we used to have a place where all the different edit counters, dashboards, and other stat tools were kept handy, but I can't seem to find it anymore, though my brain is admittedly a bit blurry right now. And we need to add that Henrik Histographer thingie, too.
TGIF!
