I've signed up as both a group leader and a lender. I won't divulge my group, mostly because there's a nagging voice telling me I shouldn't. Perhaps somewhere down the road.
Why a group leader?
Because I have a few coworkers who've expressed an interest in borrowing via Prosper. (When you're paying 18 percent on your current loans, what are you going to lose by trying to do better on Prosper?)
Setting up the group took a few minutes. As well as the usual "name, address, and contact info" stuff, Prosper asked for my Social Security Number, my driver's license number, and my chosen bank account and routing numbers.
Becoming a Lender
I don't remember exactly what I had to divulge to become a Prosper lender. If there was anything, it wasn't much more than the info required to become a Group Leader.
I initiated an electronic deposit into Prosper on Thursday morning, February 16. The transaction showed up in my bank account, and was debited, on Friday. As of right now (Saturday), Prosper tells me the transaction is still pending. Estimated completion date: February 22. (That would be this coming Wednesday.) This jives with Prosper's estimate of four business days to complete an electronic deposit. They say they're working to make this faster.
Now for the big dilemma: How to set up and track my Prosper lending experiment in Quicken?
