I had a forum at www.mysite.com/forum with a pr of 4
The fact that the forum was in a folder and not root had been bugging me for some time. Partly because I want it to rank for different keywords to the main site. A lot of directories only want a root domain so I moved it to forum.mysite.com
I have put in place 301 permanent redirects but google has completely dumped the site while MSN and Yahoo have it as number 1 page1.
I thought if you used 301 permanents you managed to hold onto any PR ??? No?
