What format should the session have? -> ECR Poster session (in addition to the one over lunch), invited talks, ECR talks, tutorial, informal talk of the PostDoc prize winner, panel discussion, etc.
On a specific topic or in general?
How much time are you willing to invest into the organisation? Can you be present at the event?
Whether one of you would be able to lead the organisation (I want to step back a bit :-) )
Whether we can use this occasion to start advertising (and asking for help for) the potential Swiss FCC ECR event that we should organise
