Please identify yourself in this photo! There are two ways to do that:

• Log in to this Wiki and edit this page. Put your name, userid, email address and location in the picture in the alphabetical list below.
• Send Dror an email message with this information.

The first option is more fun but less private.

If you are taking the class remotely or if you missed the photo day for any other reason and you want to be in the photo, send me your picture and I will gimp it in!
