Thanks Lisa, I found it now.
I recall when I was Cong Secretary that I would carefully monitor the contributions under the "New" W W Fund system and compare with the cong previous remittences for Lit and Mags . It was no where near the same and I would give a "Motivating Item" after the next Accounts Report.
Incidentally, did not Charles Taze Russell once say something like "We will know that it is time to stop when the Lord stops supplying the money!"
