Alas,things are (even more than usually) quite unpredictable here on my side. I simply do not know where I will be in April. If things do not change and I am still where I am now, April is a bit problematic, semester-wise. If things do change, I will probably be concerned with moving just then.
I.e.: It might indeed happen that I join spontaneously, but I cannot make any appointments at the moment. Jürgen
