This exactly is the point — many thanks for flagging it as such!
I'm the founder of The Emperor's Bridge Campaign. The total amount we're trying to raise is the $420 we need for our 501(c)(4) "filing fees." We have $370 so far, and we've taken all of this in small donations of $5, $10 and $20, so as to provide the greatest number of people with the greatest opportunity to participate in the founding of the organization.
Of course, I or any number of folk who are associated with this project could pitch in the final 50 dollars. But, in honoring a guy who sold scrip for 50 cents, it seemed more appropriate to make it easy for those who simply — as we say in our invite — could "buy the Emperor a drink."
