Disable private message for a certain group

[karl-os]

I would like to stop a group from being able to send or receive private messages. I can see the settings here:

 

But I cannot select "0" under conversation allowed to start per day. Is there any way to stop a group from using private messaging, or can it only be done on a per-member basis?

 

Thanks

Karl

No problem, Karl, just disable the permission to use "Messages" for the necessary groups here:
