Just a few mounths ago, I started here, but could've joind a few days earlier because I thought this site was one that charges money. Eventually, I managed to get a response from contacting and I joined c2k. I also joined CS, with the fear of getting banned everytime I go there.
But out of all of them, I like this the best of course, not just because I consider it my "home exchange", but also because when I joined, I was really clueless, but were more patient with me. (though it doesn't look like it, I don't blame em' for it, lol)
