If they made such a list in my area there would be twice as many on the inactive list as there are going to meetings.
If they are stupid enough to think there would only be a handful they need to think again, where I live there are literally more of us than there are of them.
The task of documenting them for a file would be a mammoth undertaking, that most elders have not got the time or inclination for. I can see a lot of publisher cards going missing and collective elder body amnesia occurring.
