Maybe your donators could set a lower limit of when they don't want their contribution back? Say, if you only need £20 of my £50, keep it. Something like that. Each individual according to their means/strength of feeling about this.
I suspect that although there are only 40 or so apparently active members, that there may be others who look in without logging in (our "lurkers") on a regular basis, who may still feel more strongly about the site than you think. We know how many people turn up at the 'poo bar - it's got to be more than 40.
Changing servers sounds as if it could be fraught with problems, at least in the short term. I'm no techie but you seem to have made big strides recently in getting shot of spammers. It would be a pity to make a retrograde step for a short term aim that it looks like you can solve, anyway. I'm a member of another forum and the software is awful and causes countless problems. Would a change of server affect this?
Yes, it was Pistonheads which was bought by Haymarket, btw. But it's a massive site covering much more than sports cars so I bet their revenue strength is much greater than CA's could ever be, from an advertiser's point of view.
EDIT I take Big H's point about the clash with the charities. However, I'll bet the site members here have already pledged a bit and that more will be forthcoming in June. If CA collapses in a heap then the situation will only get worse for the charities we support.
