For me regardless of all the other settings in each forum,
i only needed these ones updated.
SEE_FORUM = -1, (Forum is Visible)
READ_TOPICS = -1, (Can Read Topics)
CREATE_TOPICS = -1, (Create New Topic)
CREATE_REPLIES = -1 (Reply to a Topic)
This 1 Forum which i set up as a Holding Room.
So anyone i assign to Group 6 can not see / reply / or post a new topic or see anyother forums.
The Mass Copy for me would not work as i also have in the mix Hidden Private forums, so there are custom settings all over the place.
I Have previously used copy forum permissions for new forums but this one is chagning the permissions of an existing group.
What i see from the menus with the mass copy option is the copy all the settings from that forum to many which isnt what i had to do, i have to change a Groups settings to fit all the other settings.
