I wanted some advice on setting up user groups. My intention is to have ALL users with the Primary User Group set to "Registered". From here, my Secondary User Groups will have two purposes: styling (naming) and permissions. For example, I will have "permissions" secondary user-groups (Administrative, Moderating). The remaining user groups will be for styling purposes. The "styling" user groups will have all permissions set to "Not Set (No)", because I want permissions to be inherited from the other "permissions" user groups (Administrative and/or Moderating). So, I may have a "styling" Secondary User Group which alters things like the user banner and username CSS, etc. Is this a good approach? Also, if I had a single permission which I needed to grant, could I have a permission user-group with all permissions set to "Not Set (No)", except the single permission that I wished to grant (set to "Allow")?
