I'm just going to leave this here, since you can't receive direct messages: Dr. Keisler, I'd like to convey my gratitude for getting me through my macroeconomics exam pretty much the night before. Unfortunately we didn't have much of a lecture but I very much enjoyed listening to your on-point presentations, it's very generous of you to share them with everyone. Your students are lucky to have you. Many thanks from Germany!
