Permissions Problem|Ranks and Subscriptions

[SRobbins1977]

I'll get right into it. Our subscribers get a banner and display group for various levels of subscription which includes access to special forums, bigger signatures, avatars, and so on. Right now their primary usergroup is changed when they subscribe to do this.

However we have very giving staff and administrators. If they get a subscription, wont they lose their moderator rights?

How do the permissions work in vB? If someone could shed some light on the difficult ti read permissions documentation. Thank you.
