Well I could give £50 or £100 I suppose.
Especially if the eventual legal ownership entity gave out legal shares in Amiga.org, one share per dollar, 10,000 shares total. I wouldn't expect it to make money, although I guess the domain is worth a few grand on its own. As a company it would earn advertising revenue, and absorb "loans" from its owners (I guess there's a taxable deduction thing there). We'd have to think up a way for new people to buy in in the future, and some people to buy out (although with nominal share value of 0 there's not much point).
In ten years time, we sell up to Latin Girlfriend Finder, if there's nothing left of the community. Looking at the CPC scene, that could sadly be the case. We might have to sell up with perpetual ownership of "commodore.amiga.org" for our own uses as part of the deal :p
