User blog comment:BertH/User rights updates for Forum and Message Wall/@comment-1038387-20150120144118/@comment-26479628-20150120144353

To respond to your first question, "Forum Moderator" would not be the most accurate title, as users with this right can edit message wall posts, too, which is outside of Forum area.

Something along the lines of "Thread Moderator" would be more precise, though doesn't sound as nice. =P
