There are plenty of threads where a person can be made fun of for making an offer. Personally I do not think they accomplish much.
But going positive instead of negative thought I would start a thread where everyone could post good trades. These can be trades that you were offered and accepted or your trade offers that got accepted. Or trades that you see in the transactions list.
Bottom line it is a trade that helped both teams. Please take the time to explain why it was a good trade and how it helped both teams.
