We have put in place our new system which allows guild leaders to manage their own private guild forum. The system allows guild leaders to maintain their own private forum here on Silkroad Tavern. They have the ability to moderate topics and add/remove members access.
Existing guild leaders can manage their forums member list at
http://www.silkroadtavern.com/manage-guild. Guild leaders who would like to apply for a private forum can get more info at the same link.
