Oh well. Maybe an example can spur another solution.
We have a 100-member non-profit group that has a 10 member Executive Committee. I want an Executive Committee member to be able to send a PM to all of the other EC members. I don't want a non-EC member to be able to send a group PM to the entire EC.
I'm relatively new to phpBB but have been totally impressed by how much control I have over every aspect of the system. This one actually seems like it should be a no-brainer. And my usual experience is that it's my brain that''s the "no".
Is there some other way to do this?
