It would be tough to link someone's real name to their username if they haven't shared it here before. Or if they want to keep that information private...though it would be nice for everyone to see that certain people are donating. I'm fine remaining anonymous, or having my amount (but not my real name) "exposed".
Hell, I'll just say it: I donated $82. It's sort of lucky that this all happened on the one month in two years that I haven't been running on a budget (as I am about to go on a big vacation).
