You guys may have noticed that when you sign up for this site, you also get a profile in some other sites. What I'm asking is if any of you guys use those other sites, and what site did you first sign up for?

However, I have noticed that any changes you do to the profile in one site, effects all of the sites. What I mean is that this blog thing that I just wrote appears on all of my profiles. Also, you can PM users of the other sites even if you aren't on that site.

I signed up for GameSpot, and never used any of the other profiles given to me. What about you guys?
