Hello guys, I would like to have some sort of a marketplace section on my forum where users can buy/sell and most importantly trade. I have a memorabilia forum, where collectors want to trade their stuff with one another. Memorabilia is usually organized in collections. For instance, lets imagine that that you have a sports figures that you want to trade. Those sports figures belong to a collection "Random Sportfigures collection". Each of the figures has its own number 1-150. Here is how it usually works : You post a topic naming it "Random Sports Figures collection" And write something like : "I have : 4,5,6,15,25,45,98" and I need 74,96,112,113,150" This can obviously look pretty unorganized. So is there any trade manager, or anything that can help people out trading? How do you organize your marketplace sections?
