kneekoo: Thanks! :) For a long time I didn't use the forum at all, so I had no experience whatsoever with reputation, giveaways, how people check the scammers and so on. Recently, after I've become active in the forum, I noticed some talks about reputation, scammers, ratings... so I understood that some people are just nice, trading stuff or giving away, while others simply grab whatever they can and never give back.
I don't have so much time on my hands to play games, let alone spend hours every week (or day) in the forums, but it's a good thing I opened this thread because I learned something new without especially looking for it. So thanks for that! :)
