Amino haven't done a thing for the Amiga.
I don't know why you would want to donate to them, they are in partnership with Microfilth. All they do is publish Windoze craplets. Your money will be going into Bill Gate$ pockets, is that what you want?
It's been 7 years now since they bought the Amiga. They have done less for the Amiga than Commodore, Escom or probably even Gateway did.
They should at least allow OS4 to run on generic PPC boxes.
Many people have emailed and/or petitioned them, it doesn't seem to make any difference.
