There are lots of alternatives to paypal like-Moneybookers,E-gold,Alertpay,Google Checkout,Stormpay,E-passport,Liberty Reserve and many more.But everyone knows that leaving all the others behind paypal is on top now.And the site you are talking about as an alternative to paypal 'Revolution Money Exchange', is quite a new site and is mainly based for U.S citizens,they are good and they have really started their work strongly as they are real and also needs your SSN if you want to have an account with them.So international members like us may have no benefit now from this but hope in the future there is something they will bring for us which will prove that they can be a real and reliable alternative to paypal.
