In fact the forum originally got off the ground last year thanks to several other anonymous donations then - so anonymous that we the moderators weren't even told that any money had been given. (This was actually quite an embarrassment for me, as - not knowing there had been any donations - when I thanked those who'd given particular help to the forum at last autumn's AGM on Mallorca, obviously I didn't mention anonymous donors at all.)
We certainly owe our thanks to those original donors too.
