Yeah, but after reading your bug report it turned out to be a feature for me. Because there's no way I'm registering for an app if I have no idea what it does. Thanks Zack, this is a brilliant idea. Now just listen to the other comments about how your front page should give an idea of the mechanics of your app.
I think someone manually POSTed to my registration form and created an account with a ''/'' combination. Good thing I have input sanitization in my MySQL or the DB could be dead by now. Anyway, I deleted the account and added some server-side sanity checks.. nice observation
