Hi Andrzej (Strobel), I'm trying to find a day/time suitable for III/IV/V year students in astronomy for my monograph course - http://adjani.astro.uni.torun.pl/cgi-bin/twiki/view/Cosmo/MonographCosmo At the moment it seems that Monday 12.00-14.00g would be suitable for everyone, but it would have to be in Wydział Fizyki. Is it likely that for the first few weeks (3-4 weeks) a normal lecture room, at least with blackboard/whiteboard would be available at this time for about 10-15 students, and preferably with access to a computer projector? From about end November/first week of December, we would need access to a room with unix/linux computers, where the students can ssh to Piwnice or work locally as they wish (and install GNU GPL compatible programs :). pozdr boud PS: i tried telephoning you on x3005 but there was no answer. Email really makes communication a lot easier IMHO once people start using it.
