Problem with it is the responsibility factor(even if the forum bares no true responsibility). If deals go bad/wrong/whatever, the forum itself is sometimes looked to for support/resolution of the matter. PRS certainly wants no involvement in that. I wouldn't if I were them. Even with the disclaimer of "all deals at your own risk" - it's still a headache waiting to happen. I might be off base, but that's my guess.
It would be nice to have a board with primarily PRS in the swap, but I don't think it should be here.
