Sometimes details like this are not easy to notice and therefore removing them will not affect anything but since the system is very centralized and only the administrator gives these feedbacks I do not think that the forum can be used for trading or making deals. (At least there should be escrow members list)
Yeap, now if I bring a summary of everyone's opinions, then this feature is only for admins so this is centralized, I have already seen that Yahoo and Bitmover made a deal between them and later gave a post on that thread, after that the admin gave them positive feedback.
I wondering if in this features only have the positive feed, because I didn't see any member yet who have negative feedback on their profile. However for anything abuse, users get tagged below their user name.
