Permissions Issue

[BlueNinjaGo]

Ok, I think I see what you're trying to say.

Try this:
3 usergroups (2 primary, 1 secondary)
Group1 - Always moderated
Group2 - Never Moderated
Secondary Group - Always Moderated and can see board B

Since secondary groups can't take away permissions (AFAIK), then Group 2 will not be affected, while Group1 will still always be moderated regardless of the board they're on.
