Where do you find the LJ stats tracker?
You can use the code generated at statcounter.com If you put it in your user info page where HTML is allowed, it works fine (you can't track individual entries). I just needed an idea of how often a certain IP hit my various sites. It works in more detail on my own website. LJ limits what info is returned, but it was enough to let me see how obsessive the freaky neighbor is. :P
Though it is no longer active, using Component I had a free stat counter on -all- of my LJ pages for a good year or two.
