Membergroups can be assigned by an admin or rely on the number of posts a member has made. Let's see how to manage them now.
1) Go to Admin.
2) Click Membergroups.
The Regular Groups in the top box can only be assigned by an admin.
3) Let's add a new group.
4) Enter a Membergroup Name.
5) Since this is a post count based group, enter the number of posts required to achieve this title.
6) Select the boards this membergroup can view or Check All.
7) Click Add Group.
After the group has been added, you will be taken to its edit page where there will be more options.
8) Enter the number of star images this group should show.
Notice you can upload any image to be used in place of the default yellow star.
9) Click Save.
Our new group shows up in the list below.
10) Let's go to Settings.
Here you can select which groups can also change membergroups aside from admin.
That's it! You now know how to add and edit membergroups in SMF.
