Prosper.com announced that it is entering a quite period:

Prosper has started a process to register, with the appropriate securities authorities, promissory notes that may be offered and sold to lenders through our site in the future.

The registration filing is a necessary step toward making the secondary lending market available to the community. This is something many of you have been asking for, and we believe the liquidity of a secondary market will make Prosper even more vibrant.

Until we complete the registration process, we will not accept new lender registrations or allow new commitments from existing lenders. If you’re an existing lender, your current lender agreements will be unaffected; your existing loans will continue to be serviced; you’ll be able to track and monitor your loans; and you’ll be able to withdraw funds from your Prosper account.

See Prosper blog announcement. Prosper seems to be copying the route Lendingclub.com already successfully completed.
