Dates for people's presentations are now on the syllabus page. Check the date you are scheduled is when you think it is.
As someone pointed out, the 26th April *is* Spring Break, so people who opted for that day get moved a week later.
Welcome to the website; up finally.
You'll notice that there are no notes posted yet. I want to do these all together, the ones I should have got together for the first lecture, and complete versions from the second and third lectures, so these will go up shortly.
