I've seen it. I've actually seen quite a few of the "community" websites run by Get Satisfaction. IMDB has one and I had, a long time ago, signed up through them. I had forgotten about it, which created a conflict with my email notifications when I came on here. It was finally worked out, but it was funny that I had completely forgotten about signing up to it for IMDB to ask ONE question years before. Not IMDB itself, like I was referring to with the messaging thing, but the IMDB Get Satisfaction site.
There are actually a slew of them, and GS even has one for themselves. I perused it the other day and couldn't figure out what in the heck they were talking about. Technical stuff with GS, it seems.
