> Ole's agenda is a big improvement, as in it addresses the concerns I (and others voiced) in the past weeks. That said, to make the proceedings follow a more structured Introduction; Requirements; Details, sequence, I would like to propose the following (changes in the order of things proposed by Ole): after meeting with the chairs this afternoon, I understand their reasoning for the original agenda and I'm fine with keeping it as originally proposed. cheers, Ole > > 1.
