This is a mechanism for completely anonymous feedback to me, on any topic whatsoever. The code you type in above (and which I've emailed to your 102a-xx accounts) simply ensures that someone in the class is sending the comments (as opposed to a random person in the world). (If you want to preserve anonymity, do not use your quiz code here, but rather the special feedback code that is shared by everyone.) It is technically impossible for me to otherwise know who clicks on the submit button. Whatever you write below will be emailed to my 102a account. Thanks!
Anonymous comments for Joe on the 103 course (please hit RETURN at end of each line, rather than depending on wraparound): (This window scrolls indefinitely, so you can type in an arbitrary number of lines of text.)
Press to submit your comments, or to reset all fields. You can reset and submit second thoughts if you like. Thanks!
