No, i actually increased alot! But for the period of 3 months! I got pr2 on inner pages now! But the home page droped from pr 4 to pr 3
My site was created in 2001 bro. Check these data centers, most of them still showing pr 4, but some of them are showing me now pr 3, http://livepr.raketforskning.com/?u=www.infatex.com i never had any pr 3 before!
My sites one started 98 the other 2000 were PR 5 until the big PR update in 2005, then they both dropped to PR4 but both gained and held better ranking for some key KWP So don't sweat it unless kwp dropped.
