uhh this is pretty much the situation for me:
I'm GMT +2. Today I'm free all day except the evening, tomorrow i'm not free in the morning/early afternoon, saturday i'm not free from 7am to 5pm, and sunday i'm not free in the afternoon. Next week i'll be in london and we can't play at all.
So yeah, saturday night (my time) is probably the best. What about 8/9/10PM my time, 10AM/11AM/12AM your time?
