Well, I wanted text that was specific to each forum. While this code is what I'd want sort of, I kind of needed something more elaborate.
I was envisioning something where it was in the control panel, you could turn it on/off per forum, and have somethign in the forum areas that showed what the "post intro text" (I admit I can't think of a good name) would be for that forum.
The code above is fine if you want just the same simple text in forum a,b,c,d - but if you want different text in said forums (or others/whatever), I think something more elaborate might be needed.
