Group owners (who are also moderators in my setup) can send out invites to a forum, but when doing that, they cannot set up adding the invitee to the group they own, the group name field is not available on the invite dialog. Only admins have that field shown.
Also, when using Admin/Users menu, moderators who are group owners cannot add a user to the group on that page. Right now the only way for group owners to add members to their group is through the Admin/Group menu. Am I missing something or is that a missing feature?
