Well this was bound to happen. We knew it. You knew it. EVERYBODY knew it. We had to finally add in some requirements to ensure validity on our accounts. It's a sad day...
To be clear, it was intentional to allow everybody to just come on into VITY and get straight to work. Really, we freaking LOVED that about VITY internally. Just as painless a signup process as we could deliver. "We'll verify you later", we thought. But, as most expected, things got a little out of hand there.
Too many unverified accounts and too many undelivered invites. So now you have to verify your email before you can do pretty much anything. In fact, the only thing you CAN do is browse around and verify your email. No profile creation, no application, certainly can't earn any money, and VITY just won't be that much fun.
Still, should be painless enough. You'll get an email immediately upon registration and you click a link. Easy peasy.
