UBB.threads PHP Forum Software Community Forums UBB.classic UBB.classic 6 Support Registration Queue Question

I am using UBB.classic 6.3.0.1 and want to get rid of someone from the Registration Queue, but I do not want email going out to him, nor do I want to delete him from the database. I just want to pretend he doesn't exist, but still don't want him re-using the email address.

How do I do this? Thanks for any help!
