Enforce Access Permissions

I’m planning to use Revolution for a support portal.

Almost every page, apart from intro and login, will be secured using Resource Groups and Access Permissions.

How can I enforce a user ticks at least one Resource Group under the Access Permissions tab of a Resource?

Currently the default is they’re all unchecked so a Resource is available to everyone. I’d like the default to be the other way round so they’re available to nobody unless a Resource Group is checked.

You should be able to use a plugin to accomplish this.
