CMS How to make a user a moderator of a specific forum

[محروم.كوم]

I have a group.
In that group I have 3 volunteers, I also have another member who is the 'head' of the group.

All members in this group have access to a secret forum.

How to I give the 'head' of the group moderator privelages for a specific forum, a forum which the whole group will be working on but she will be in charge of.


Also the group hasa set rank, but I would like to set a specific rank for the head of the group? How do I do that?? __DEFINE_LIKE_SHARE__
