If this is in any way serious, the way to go is to set up a non-profit organization for the purpose of purchasing and running this Amiga Community site. This entity would take tax deductable donations, run fundraisers, and run other promotions to fund the site. This means that there would be a board of directors, a site admin plus moderator staff, and possibly paid membership that would confir voting rights along with other perks.
I feel to do otherwise is to bring chaos and disaster. I would hope Wayne would refuse any offers other than sole ownership or like the above. There simply needs to be organization.
