... the Googlebot and the yahoo thing were it says members on?

I have wondered the same thing, I'm not sure what they are, but I'm guessing, (pointing out the blatantly obvious) that they're not real members in the forum

Maybe there people from yahoo/google doing there job, finding the riht sites for the right typed info in the space bar...

They are search bots, they crawl websites and gather information and will ultimately add this website to their search results page (if people search for the right things of course).

Huh, I guess you learn something every day, that's pretty interesting.
