Beginning on 1 June, this website will be updated for the ShanghAI Lectures 2012. This means that the 2011 study group pages will be "locked" and students from 2011 will be "converted" into normal users. If you were a student in 2011, you can continue to use the website, post on the discussion boards, etc., but you will not be able to participate in the 2012 exercises and get new points. In case you are a student who takes the class again, please send an e-mail to Nathan Labhart and explain your situation. Thanks!
