Dear Colleagues, thank you for your interest in the Colloquium on Combinatorics in Magdeburg, November 16 and 17, 2007. Here is some more information about the workshop: 1. All lecture rooms are equipped with a data projector, black and/or white board, overhead projector. However, it may be impossible/difficult to use the media in parallel. For the invited lectures: There will be two overhead projectors available. 2. You may find a list of participants on the homepage http://www.math.uni-magdeburg.de/kolkom/ of the conference. We will include a list of abstracts soon. We expect that the program is ready by November 5. 3. If you arrive on November 15, there is a chance to meet in the Restaurant ``House of Steaks'', Magdeburg, Otto-von Guericke-Strasse 104. This place is not far away from the station. It is the same location (though different name) where we met 4 and 5 years ago. You may receive the conference documents there between 6 and 10 pm. 4. There will be a conference office (open both days of the conference from 9 am to 5 pm) in Room 215 of building 02 on the campus of the Otto-von-Guericke-University, Universitaetsplatz. 5.
