Is it possible to have a "Trade" thread?

Just practicing my General Maintainer role, Is it possible to have a thread for people who want to trade their GPSr or related accessories? It should be very useful and worthy thread giving the number of members in the forum. And, in order to avoid scams and sneaky traders we might have some rules to post in this thread, such as you should be a star member for example to be able to post.

What is everybody thinking regarding this?

If this idea turned to be worthy, I will be glad to help the moderators maintaining such thread and/or putting its rules.
