Thank you those of you who let me know the donation button was broken. It turns out there is a fundamental incompatibility between the way PayPal generates their buttons and ASP.NET, so I removed the button until I have time to figure out what to do (if anything).
In the meantime, sorry that I’m not around to chat and explain this stuff in person, and that I actually let several hours go by before I addressed the situation. I’m amazed and gratified that people apparently want to throw money my way so badly, but every now then this nasty little thing called “my job” creeps in and demands my attention. Since they’re throwing more money my way, they win the battle for my limited attention span.
