I just answered that did I not? I am confused now. If you change a name of a usergroup in the forum you need to type the new name in the edit usergroups window for that group in our usergroups editor cause the cache does not let you change a name.
Now you add a new usergroup in the forum and you hit refresh usergroups in our programany new groups are imported. If you think this is not happening you need to give us more info cause we have 16 different integrations so we need to proceed from the basics.
