I'm sure that there are many people who would be willing to take on the website, even if there are costs involved. I'd consider it myself, if I knew the first thing about web forum hosting - I suppose that's where a good team of staff members comes in handy.
If this announcement is indeed true, then I would imagine Wayne will strike some deal to ensure the survival of the website. He may have had enough himself, but I'm sure he wont want to see the entire forum killed over this. I mean, it's not like he has any reason to see the forum die out of spite or anything silly like that.
Cheer up Amiga.org'ers, I don't think these will be the last days you enjoy hear at a.org. It may have a different domain in the near future, but that doesn't make it any different a website. All is not lost.
