Reseller...WebID Question


I’m reselling some of my space/bandwidth and the users want to know how they can add their own e-mail accounts, check stats, etc. I know this topic has been ran into the ground, but I have a specific question about it.

If I create an web id for a user, and grant only privledges to their domain and nothing else, can they still renew their domain and it show up charged to my account?
