What do you mean we don't keep lists? Why, some churches have current membership lists stretching to the early 1800S!
Those are just virtual lists made up of dead people, dead beats, and dead heads so that when the pastors get together they can brag about something, find out who is paying their tithes and offerings or when they get into trouble it will be impossible to get a quorum since they can't find the people. Actually, Baptists don't have official lists; they are moved to come together by the Spirit,like "the wind bloweth where it listeth and thou hearest.....," especially when there is food available or an argument to be had.
