Are you waiting for Steemit to confirm the screenname that you registered for? If so, I would check the spam folder of the email you registered with. The confirmation email with confirmation link from Steemit could have ended up there. After you submit for a new account and verify with the code(mine was through text message on phone) Steemit sends, then Steemit will send out the confirmaton email. It may take a few days but a week seems a little long from my experience.
