I gave the list with the participants to the administration. For those that had not been on the list and who added themselves in handwriting to that list: I gave also that to the administration.
They told me, in case you are not on that printed list, it's a sign that you are not properly registered in the web/studentweb, so you should do that.
The administration will contact you via email today, and tell you about it. I guess, they can help you also in case you have problems registering.
