Thank you again to the 50 (!) people who responded. A first followup
after a meeting with Iolanda yesterday. There will be more later I
think, e.g. this month there is a meetup to talk about program.*
The registration form will definitely include an option to donate some
money for the scholarships fund. There was a substantial interest in
this option. We plan to provide partial scholarships/discount codes of
300 € each, see also
https://meta.wikimedia.org/wiki/Wikimania/Scholarships/2016 for current
budget info and of course
https://wikimania2016.wikimedia.org/wiki/Scholarship_committee .
As for the question on (variable) costs, the answers varied a lot. The
registration form is also expected to clear up any confusion, because
every single service/offering will be labeled with its actual cost. Any
unexpected saving will also go back to (future) Wikimania scholarships
funds or similar.
