Both dates are fine with me (I MAY have a training on the 16th in Munich, meaning I'd have to leave earlier on Sunday).
No need to pick me up, Oranienburger Str. should be managable for me.
I just hope, that my ACS skills will improve (last time I worked with ACS was in spring 2001 with Dirk and later Peter and Timo). I can cook coffee if I should be of no other use...
