bamalucky has it that the ability to view old listings will be restored in some form in the next week or two:
Tom Underdown just called me to tell me that old listings would be back in the next hot fix.
ETA:By next week
Tom is Prosper's Lender Services Manager. This has been a hot-button topic for lenders in the forums with a significant amount of time spent decrying the change. Lenders feel that reviewing past listings, especially for those that were fully funded into loans, is educational and helps provide guidance for future lending. Prosper is worried that the listings expose too much personal information about potential or actual borrowers.
