Primary usergroup in UCP?

[RaeHoward9]

Hey,

no the group leaders thing doesn't work. I can set the group leaders and stuff, but if they change group members in their UCP, its only changing the additional user group, not the primary group or displaygroup. Without this, that function is quite useless. I want the moderators to manage all this without the ACP and without user action (half of them won't ask to join, forget it etc.).

How do I write a plugin for this?
