Set the Basic permissions. These settings determine who can have access to the group. There are three areas to set: View Topics, Post, and Join the group.
By default a group is private. To change it to public see: Make a Group Public .
After filling up all the sections click the Create Group button on the top left of the screen.
The new group has now been created.
Note:Once a Group is created, there can sometime be a short lag period while the server creates the group, assigns permissions, etc.
