I have made my calendar public now. Well actually it has been public for the last couple of years, but now i put it online on this site, to make it easier to find. It will probably be used mostly by people around me who want to book meetings with me, so it might not make much sense for complete outsiders.
If you are interested in having a coffee with me, please find a time that is available and contact me. I will try to have the calendar up to date as much as possible, to make it a useful tool.
