it seems like Prosper may be re-launching tomorrow as an approved service. I hope its true, and good luck to Prosper. I noticed this morning their site is down, and it actually does nto say maintenance as noted in the quote below, but "configuration changes".
Looks Like Prosper.com is On Its Way Back! | Prosper Lending Review
Paraphrasing Anthony’s email he says that the US SEC approved Prosper’s new securitized note trading platform at 3:30 PM on Friday, and that they pulled the site down over the weekend through Monday.
Looks like we might get (another) launch tomorrow from Prosper.com. Really looking forward to seeing them back into the P2P world.

To be clear the ZOPA stuation is only the Italian company .. as you say zopa.it
