Reading Lady Lee's post about collecting Public Talk Outlines made me recall the following:
When I was the Public Talk Coordinator and Cong. Secretary, I kept the Public Talk File. The Society sends updates on ocassion to the P.O. (or Secretary when I was serving). So, I had a complete file of all talks. Each Elder in the Circuit is assigned Talk Numbers and Titles, so that when we scheduled talks, I would go to the Elder Registers (we had more than one circuit, which allowed for me to have several registers) and call each Elder in various congregations to ask them to give talk number so-and-so. The register showed the Elder's name, assigned talks, phone number, address, and Congregation.
This was a tricky job, because we would meet as Elders and decide what material the congregation needed. Then, we also wanted to make sure all the talked were eventually covered, so that we did not hear the same thing very often. We did avoid some of the more boring talks, as the Society never gave much direction on how we handled this aspect. I kept a self-made form (spread sheet) that showed what talks were given when, and by whom. This enabled me to make sure the talk topics were spread out as evenly as possible over the year.
We graded visiting Elders (and local Elders). We would sit with a copy of the outline when an Elder gave a talk, then note if he followed it or deviated too much. This practice was introduced in the mid-1980s, after the big Apostate scare started. We were supposed to assure that the speakers were not introducing apostate thinking. We then used an A, B C D, of F grade system. This was not done at the explicite direction of the Society, but the CO would ask us who we thought were good speakers in the Circuit. The A, B and C speakers never knew we graded them. The D speakers were counseled privately in the library and told how their talk sucked, and what we would be looking for in the future if we ever invited them back again. The F speakers were told the same thing, and we called their P.O. or other Elders to report them. If the bad speaker was a P.O. , then we would call one of the other Elders. We would tell the F speaker that he would not be reinvited to speak at our Hall again. Oddly enough, this never created bad feelings, or caused any stir with the CO. I suspect that bad speakers were relieved to not have to give anymore inane and boring talks. Though I am sure some were privately hurt.
