OK. Well, I’ve got a very similiar problem. I started promoting my site, http://www.24-7wagering.com, in February 2006. The only page that is indexed is my index page. And that’s still at a PR2 even though I’ve updated the site just about every other day!
A page rank predication page (http://www.iwebtool.com/pagerank_prediction) shows me at PR2, but predicts me at PR4.
What gives and what am I doing wrong?
