Maybe if he just starts posting on the existing SO thread, others will follow. Or he can do what has become the norm here and just start a thread wherever, any time a random thought pops into his head.

When I was still moderating we discussed reorganizing the board but I felt it would be a wasted effort since folks don't seem to have any rhyme or reason where they post. It's that way with every board I've seen,
When I come on, I always just hit "view active topics" and any thread with a yellow page icon is one with a post I have not yet read. I suspect that is how most people do it. If I am looking for a specific topic, I go to the board index or use the "Search" button. The latter is usually more efficient.
Tell Mr. P we would enjoy hearing from him!
