At our recent ca this letter (or possibly one very similar) was read out when the financial statement was presented to the whole assembly. Earlier, in the elders meeting, there was a lot of thinly disguised hostility towards it - elders have learned from what has happened in their own congregations after sending all of their money in. As a result, although a large donation was sent, sufficient was retained to fully fund 2 or 3 more assemblies - they said they were going to be very cautious about how much was sent.
