Here is the reason given for eliminating this function on lds.org, I thought they had some good suggestions. Obviously we need to correlate the schedule between HP, EQ and RS if we are going to put them in a program or make announcements, put it online etc. Somewhere some manual says that you are to skip a lesson rather than slip the whole schedule when Stake Conference happens. I think the reason it was little used was that many didn't know about it and bishops were never instructed to use it.

We understand your concerns, the Lesson Schedules function on LDS.org will be discontinued 31 December 2016 due to the cost of needing to update the old technology for a program which was being used by only 750 of the 30,000 wards and branches in the Church.
1. Print a schedule of Gospel Doctrine, Melchizedek Priesthood, and Relief Society lessons and give them out at the beginning of the year.
2. Post the next lessons in the weekly announcements in the Sacrament Meeting program.
3. Post the lesson information (lesson number with link, lesson reading assignment with links, teacher ) in the ward calendar. Ward members can access the calendar on LDS.org and on the LDS Tools mobile app.
4. List the lesson schedule in a Word document and share it on Facebook, Google Docs, or Dropbox. See internet.lds.org for Church internet guidelines: https://www.lds.org/pages/online-resour ... b-internet
