I challenge those who can afford $5, but who haven't donated to at least make a small/token donation - they will feel better about themselves and I'm sure they realize this.
I will also offer to pay $5 each for the first 10 FReepers who really can't afford it and who privately ping me - I'll keep it quiet so they don't have to worry about being "outed". If I get more than 10, I will pass the numbers, sans names, on in case someone else would like to step up.
I also challenge other FReepers who can afford a little bit more to do something similar.
I love liberty and FR and I gave. Please, others give, too.
