Costs were just announced as over £9000 (GBP) for a one day assembly here in Dundee, Scotland at an old rented town hall with about 1000 in attendance. (Capacity would be around 1300)
They apparently sent £1000 towards the new bethel project in Chelmsford out of the circuit funds.
They spent £300 on a projector which had the sole purpose for the day of projecting 1 Pet. 3:11 on a screen - that's all.
Donations for the day were apparently fell something like £2000 short of the "costs", so I think they must have already collected over £6000!
Coincidentally, the visiting "bethel" speaker was one of the guys from the new million pound translation office in Bangor, Wales.
