The volunteers post daily with great informative data but each of their posts is unrelated to the others on any given board other than the fact they share a classification. Why on earth would you want to restrict their data in this manner? If their posts don't interest you - then don't READ them and don't search for them. Would you also restrict OTHER data posters or ask them to combine unrelated posts into a single thread?
Why would ANY poster attach additional posts on UNrelated people/subjects into a single thread. Also, suppose something is in error and needs to be deleted (I've had the Teafor2 posters ask on occasion to delete a post so that they can make a corrected post) and in the middle of a thread this wouldn't be possible.
