If I search for: "gaim forum" on Google, the first result is

forum do gaim no sourceforge
sourceforge.net/forum/?group_id=235

It's interesting though, that the page title displayed by Google is not the real page title, but the text of a link made to that site, at http://www.tocchetto.com/felipe/

Sorry if this is a known issue/thingy.

This is rather new, though it has been discussed previously. Sourceforge disallows crawling of "/forum" via their robots.txt, so Google cannot access the actual page title... so they resort to the next best thing, backlink text.
