Lanny, I'm not on staff, but I can answer your question.
If you look at the dallas forum, think of that as the "parent" forum.
Open the dallas forum and you'll see "questions for the staff", "welcomes and intros", "provider ads - dallas", "provider ads - fort worth", etc. Those are the "child forums" in the "parent" dallas forum.
Nothing sketchy - just standard computer speak that sounds sketchy when applied to this particular topic.
