The site is
www.psp-forum.com
Ive removed session ID's for guests, and the pages are HTML.
But only the homepage has been indexed :S
<EDIT- just noticed robots.txt>
However, Ive noticed a prob in robots.txt, ill remove some of the listings and see what happens.
Ive done quite a good bit of seo on that site (aswell as starting to get links), eg removed all links to usernames etc in guest view. (I had removed the "who is online" bit at the bottom, because it is extra irrelevent links to googlebot, but i decided to put it back in because I feel from a user point of view its useful to see whos online).
