You can also increase your chances of winning by using your special referral link and getting your friends to sign up. The contest runs through January 31st and you can enter up to 25 times. As you would expect there is plenty of fine print on the contest but nothing I read that would cause concern.
I am not a big fan of promotions like this because you get a bunch of free loaders who never have any intention of becoming a borrower or investor. But they might generate some marketing buzz by getting media coverage and it is a pretty cheap way to create a list of potential prospects.
I get no kickback from Prosper for mentioning this contest – but it is a free $1,000 and it takes roughly 15 seconds to enter. So go at it.
