It's understandable really. Most other "marketplaces" are either a company that only allows their products, or some dude's site. Mike (owner) provides this forum for mainly support purposes and allows FS items as a nice gesture... an added benefit. He doesn't take kindly to other companies selling their stuff on here, or individuals just registering to sell their stuff. It costs quite a bit for this site with no real profit. Makes sense when you take all this into consideration.
And; thanks!
