Love the website, great idea. I don't have a problem more of a suggestion really. I would like to talk this site up, thought would be if you could create a "invite" type option so I can send this along to friends via email. Just a thought. Thanks for a great site.
I've had so many bad experiences on other sites with features like that (and they're often turned ON by default and you accidentally email 50 friends) that I don't think we'll ever add something like that.
I'd rather rely on old-fashioned word-of-mouth, so if you want to invite friends, just open up your address book in your email application of choice and send them a link to the site!
