I agree on trying to get more server members to donate. But I do have a potential problem with badges for reg donators. Even if it comes with no other reward than a badge, that could become a status symbol. And that could have an effect on social ecosystem.
I do think a more visible donation button is a great idea. It would be a constant reminder, and ever avail. Admins can also regularly post donation requests, and one and done thank yous to reg supporters.
