I can't do Friday the 18th, as it's Good Friday and I'll be in a chapel somewhere pretending to be pious. 25th is also dodgy as it's the eve of my birthday, and I'll be in Lithuania. Any Friday after that should be fine, however, as is this Friday (11th) provided we start lateish.
edit: that being said, if you want to start without me, I won't mind. On the other hand we probably could get through all that in one night.
