Here's something interesting a friend sent me. There's a pretty cool replica of the message boards for shows, movies, and even actors. Here's an example of the MAGNUM PI site: http://www.moviechat.org/movies/tt0080240
. As you'll note there's no episode guide there or cast information but you can see various threads there which existed on IMDB. I don't see the most recent ones, the earliest one is from 13 days ago (created by me incidentally). Looks like this site is for message board purposes only (hence the name "moviechat"). So it's like IMDB but with *only* the message board option. You can search for other shows and movies. Unfortunately I don't see anything on the FIVE-O site, but I do on the FIVE-ZERO site. I'm not quite sure how these got added or who added them or when they were added. Some shows have the threads that existed on IMDB and some don't. But you can always add new ones.
Anyway I thought this was interesting.
