Dwolla is extremely safe, and is a competitor to PayPal. It has been around for a while now. If you trusted the evil Paypal, you should have no problems trusting Dwolla.
In fact, they do background checks when you make an account with them. We tried to make a joint account and just used a combination of our names, and our account got shut down because we weren't a "real person" lol. Fixed that now though.
To whoever was wanting to sell their 5970, you can probably make more money mining with it than you will sell it for. My advice is to keep mining with it, then when you aren't seeing as much of a return, sell it if the price is still at a premium. Or I'll give you $100 for it right now. (or even $100 worth of BTC!)
