Forum phpBB question

Have a couple of questions about my forums. I finally figured out which pages to exclude from my sitemap.xml file from google. So now I have my main pages all listed (good thing).

The bad thing is that google isn’t listing my forum pages at all. they have this url

/forums/viewtopic.php?t=6

I changed it from the sid endings to the one above but it looks like google still knows it is a session id?

hmmm… anyone got any feedback?

Anyone know how I can make my forums have the title name in them, like they do here?
for example bb/major-problem-with-mg-software-update.8766.html?

Thanks for any help
