Yes you must write the forum ID's manually... I have this working down on 3.7 so I'm 99.9% sure it should work on 3.8.2 with the correct code edits. I am familiar with recursive functions but honestly don't see how it would apply here. I debated making the forum id's a declaration in only 1 place but I thought the code was neater this way, obviously if you know what you're doing you could do it either way, the crux of this code is merely the placement of the "If" statements and the WHERE clause.
