The google bot trawls the web indexing web pages for it's search engine. It's impressively active on this site. We get re-read more times that most businesses, which is a complement to the HCI of the site.
I set up special accounts for the various bots, on the new forum to help them do their job better and to keep track. Since the new forum went up a few weeks ago we've had the google one, the yahoo and the msn. So we should appear on at least those search engines.
