Damn, that IS hidden! No posts since 11/17 - they did a good job of making it disappear while still being there 
They successfully gutted it, and with good reason. They wiped most all of the posts from the prior lenders & have set moderation on high so that new posts take forever to get on there.
Even after Prosper's last stand of high moderation & wiping .Orger's, that population of lenders still became...
how should I say... self aware of how crappy Prosper's performance was.
No matter how many times Prosper wipes the forums & not matter how much they try to cleanse the system, when you put lenders together, they will eventually figure out how poor Prosper performs. The end result is always a bad PR nightmare for Propser. The only thing worth having on there is a forum for developers.
