Clarification about Askbot and Exercise Submission
For the theoretical exercises(those that do not involve attacking/defending a system), there is no need to hand in anything. In particular, this means that you do not have to hand in anything for exercise sheet 1. If you have any questions that do not leak solutions to exercises, we ask you to place them in the Askbot, a StackOverflow like forum in the CMS. This way, your fellow students can help you with your questions and any answer will be public.
