They have a $5/month "starving hacker" subscription level. Morally you ought not to use it if you can afford more, but I expect they'd rather you use it than give them no money at.
Personally, I pay for "project leader" level ($16.00/month) so I can give them a bit more... But I'm not up to "maniacal supporer" ($50.00/month)!
