Adam,
As a new user I hope you don't think I being too pushy, but If I have been thinking about this and would like to make a suggestion, or two
If you make the Administrator Role and the Registered User role as defaults then if the additional Roles can not be matched to exisiting, already created roles make the roles for use with CS named as CS Advanced, CS Normal, or something that would denote them as roles specifically for CS with a consistant prefix so they will be grouped in the Role Manager together.
Make sense?
