Agenda+ Geneva F2F September

Survey created at [1], should now closed.
Can we confirm as a resolution that we will proceed with this meeting?
If so, agenda discussion needs to follow – we have limited time today given the actions and issues so this is a kick-off rather than a concluding discussion.

Wiki page at [2] including draft agenda – now with accommodation and flights section.

Agenda proposal from Pierre for 9am-midday on day 2 to resolve blocking IMSC 1 issues.
