It just dawned on me...
A while back the LDC requested addresses of all publishers in each congregation to many of the congregations in our area. Of course, we sent it in not questioning what the data was for. We were later summoned to a meeting with all the elders from these congregations. The data was to see which congregations would benefit most from the new KH that would be going up through the LDC arrangement. It was interesting to see how they mapped out and color coded each home. (The showed it to us on screen)
I wouldn't doubt it if this data was collected from all congregations through the LDC arrangement - thus no official watchtower letter. Perhaps they are using all this information for the purpose of sell offs, rather than new construction.
Did any other congs. have to send in publisher addresses?
