I got Page Rank 2!!

Without www. I get 0.
With it, I get 2/10.

Assuming I check all the site with www, at top25web, CheckPageRank.com, Blogflux and PPP PR checker I get TWO!

But at PRChecker.info, eelek, pochik, may yow, none, ZILCH!!

Anyone can tell me how come?? And also hor, when I tried to add the html into my blog, somehow I get PR 7 or 9 leh? Good also if true. So how do I change that? It's 3am now that's why I can't think straight. Pray tell arrr...
