Blondie -- I see it damn near as tithing already -- just on a Circuit/Cong level, vs family level. WTS tells the Circuit how much they must pay, No such thing as voluntary giving any longer. If the demanded amount does not come in from the Circuit, then the Circuit tells the Congs how much they must pay (per Publisher). If the demanded amount does not come in from the Pubs, then the Cong is forced make the payment and the Pubs still have to cover the "donation".
WTS has a guaranteed donation arrangement now.
