Join member group & allow access to sub-forum.

[Jordan17]

Lets say I have a sub-forum called TV Shows. I create a user group that members on the forum can subscribe to in the User CP by ticking a box.

When they have subscribed to this group, they will then be able to get access to the TV Show sub-forum. Otherwise, if they aren't subscribed they will not be able to see inside the thread. They will see a "You need to subscribe to this in order to view. Go to User CP and join this group" error message.

Anyway to do this?

PS. How would I set the variable so that this group that members subscribe to can check if people are within the group or not. For example, if I set up the group called Group20 and its id is 9, what would the variable clause be to check if someone is in this group...?

EG. on the nav bar....<if condition="$group['9']"> DISPLAY LINK</if>

How can I do this?
