Bloodfrenzy, I already PMed you about this, but I'll respond here as well for other peoples' benefit.
We _DO_ have a system in place to bring up trade disputes in the form of
Transaction Reports.
Simple rules for Transaction Reports:
Keep it nice and to the facts. You can post details of the trade that you had issues with in a Transaction Report (do not post personal info like outside emails/phone numbers/addresses/etc, however). However, we ask that you refrain from calling people thieves/scammers/etc as
that is a violation of Dakka's Rule #1, and we generally try to give everyone the Benefit of Doubt and allow them to defend themselves. Facts of the issue alone should be enough to let others judge if they are willing to deal with the trader in question.
