As has been mentioned, here in the UK the use of S8's was dropped some years ago. However about two years ago we received thousands of the forms with our literature order and they were deemed OK for use again.
The fact they have now been discontinued fits in with several other changes.
The CO's report to the Society has been changed with most of the detail removed. The names of elders and MS's he has appointed/removed is not reported to the Society nor are average meeting attendances etc.
The S-79 form which the elders fill in after someone is disfellowshipped is no longer sent to the Society, it is kept in the Congregation File and any additional comments they feel should be made cannot be put on the form but only on a blank sheet of paper with no congregation/WT headings etc.
All these changes are keep the WT society away from any member that may cause them legal problems.
