Usually, if you find URLs in Google with no description or title, that means that Google has found but not spidered the pages; the two cures for that are time (keep waiting) and inbound linkage (historically, better PR has meant faster and deeper spidering).
Do you have the archive enabled? Note that your PHP installation influences whether this will work - if you click on the archive link and end up back on the home page, PHP hasn't been installed as an Apache module. For vBB forums that have been around for a while, the archive pages seem to outperform the user pages as they have friendly URLs and none of the fairly massive overhead of a typical vBB page.
