No tithe. The org's wolves will just remind the sheep of the Bible "principle" of the widow's two small coins - to give as much as you can.
Congregations will then be informed that the "faithful slave" is introducing a new & more efficient method of collecting donations which will conserve valuable funds - donate regularly via bank transfer.
Now every JW can be "encouraged" to donate, because the wolves in the KH can now monitor the "sacrifices" of each individual - just as they presently do with the Monthly Reports.
