There is apparently a huge mix-up in days and seminar groups this week. We have a Monday group (seminar groups A and B) and a Tuesday group (seminar groups C and D).
This week only the Monday group doesn't meet on a Monday, but rather tomorrow, on Wednesday. I don't know why that is, that's just the way the schedule looked when I got it (there is not specific intension of mine behind this "anomaly").
Unfortunately several persons who are in groups A and B showed up today, and I also believe several persons in groups C and D will show up tomorrow even though they were supposed to meet today. There's not that much to do about it but to handle the issue at this point in time.
I do however want to point out that a question (by anoyone!) on the blog yesterday would have been a good way to avoid the confusion! Also, please see this earlier blog post about the times and dates for all seminars if there still is some confusion.
