I decided to sign up over at Revolution MoneyExchange to nab the $25 sign-up bonus, which they're offering until May 15. The service allows you to email funds back and forth between friends. The sign-up process is quick; there is no hard credit-check against your credit report; they're backed by some serious financial heavies (Citi, Morgan Stanley, etc.). Google around a bit - they're legit. They want you to take this money, because it means another customer for them.
Hop on over and grab $25 - in the interest of full disclosure, they scoot me $10 when you sign up as well, but I'd be telling you to take the $25 either way. Like the title says: there is nothing at all like free money.
