@MatiasJJ @bast, there are places for you to fill out here (or let me know the general idea and I can write), I think you know the current best practices / problems better than me. Remember to add yourself as an author if you modify!

Thanks a lot. I will carefully read and comment since this is a problem I am thinking about a lot these days and also we discussed this earlier today in meeting.

I will work on registration coming week and then this will nicely fit into my work.

Finally reviewing ...

Points to possibly add/expand:

1. No-shows are a problem in any event but it is an extra problem in our team-based setup where we try to form teams and match teams to exercise leads. It is a problem then if either most of the team does not show up (this has happened frequently) or the exercise lead does not show up (this hasn't happened much). The fact that some exercise leads felt "unused" is for me the major problem to fix in upcoming events.

2. Problem with distributed registration: this may be clear to all organizers but not clear to the learners. Especially if all registrations don't open at the same time, the motivated learner may register in the "wrong" one which can lead to confusion in communication and team formation and show-up-expectations.

(2) is a good point! distributed registration makes things easier. but then multiple-registrations means there will be no-show in one or the other, making more work.
Will update with this.

I would like this to not get lost but also we have moved on a bit. Will it help if we meet for a 45 min call and finish this live together and get it published?

I am sorry we never got this merged but maybe we can update it with lessons learned from March workshop and plan for the September and future workshops?
