Dear all as you have seen: I have sent out the invitation to students (only six, for now) to help with testing the online tutorial. I have hesitated a bit because not all of us (but me) have yet done a final pass over the whole thing. But I think it is in a shape that will certainly not make a bad impression with the testers. And better find the bugs early than with all of the students. I have made another pass over the tutorial and have patched minor issues. *Repository*: I have copied the content to text-files that now reside in our repository at https://svn.inf.ethz.ch/svn/lecturers/vorlesungen/trunk/tutorials (all of you have RW access). *Further changes **should be made visible there *by simply copying the content of the respective chapter into the text-file and submitting it to the repo. Therewith we can now avoid issues with losing content, which, by the way, now happened just before I put the things to the repo. Moreover, we can keep track of what changed. Most of my changes from today are documented this way now, for instance. Thanks all of you for your efforts, in particular for helping last minute today! Best Regards Felix
