Prosper is showing as a soft pull on all my CB reports.
ETA: Just checked Transunion... Prosper is showing 1 soft pull and only 1 payment, Oct 2007, though the "outstanding balance" reflects all my payments through December. I'm thinking prosper reports 2 to 3 months in arrears. Annoying. 
In other news, I just discovered I have an unpaid parking ticket. Awesome. I've only ever gotten ONE parking ticket, and I paid it immediately (parked on the street during a street sweeping day!). DAMMIT!ETA2: Sorry for the confusion, I must have mis-read... Prosper isn't showing anywhere else besides my loan and payment history. No promo/soft pulls or anything. As for posting payment history so late, my car payment is only showing through October, too. Maybe that's standard.
