OP is only trading with members with some trust. Although I would advise him to contact trusted people via PMs instead of making a new thread about it. As there are lots of members with high trust doing exchange services, I'm gonna be bold and say you are doing this just to increase your trust rating, no offense. Another thing, how much do you consider "high trust rating"?
I took your advice and PMed a couple of people. I only created a thread because none of the "trusted" sellers were online; but looks like I didn't get any trade requests that I would actually consider.
I would prefer to trade with people with green trust/lots of feedback.
Anyways, I'll close this thread for the time being; I think I'll get a trade with one of the few people I PMed.
