As the first two posts are from people that have just joined and their first and currently only post is in said forum. Do you think it would be good to add the 50 post rule to this forum as well? As even if they got a price for it, they could not sell it unless they started posting...
Assembler has already stated that the forum can be used by people who are looking to buy (and therefore get a baseline price as to what they should be looking to pay). And as the market place has no 50 post requirement on WTB, I dont see how that could work.
