You can do this. BitcoinStarter.com was the first to enable this. They are coming back online this week at some point.
Isn't that arrangement gonna depend purely on how legit the website is feeling? And coming back online don't sound too reassuring. I guess the OP is talking something automated.
They didn't come offline because of anything just re-development of the website. At the time they had a way to refund all bitcoins to everyone automatically.
