Yesterday a student asked for five minutes of my lecture to talk about voter registration and hand out registration cards. I asked students if they'd like a link to a site that they can use to look up whether they're currently registered. Today I found the link and posted it on their class web page: http://www.canivote.org.
Also did my click-to-donate sites this evening. This is my long, 3-lab day, so I'm tired out in the evening. But I cheered myself up with my favorite "Call me Maybe" take-off video: Cast On, Baby!
