I'm really sorry about that, I've never heard of anyone having that much trouble. We get a lot of successful registrations every week, so I generally assume things are going well.
He can just drop me an email (from the email he was trying to register) to let me know he's having troubles and I'll manually approve the account. There's a forum feedback link that most people use, but he can also just send it to admin08@siouxsports.com .
