as you know, there will be a Hackfest in Munich from September 2nd to 4th.
We have the offer from a service provider that they sponsor one round of
food and beverages for all attendees, roughly about 250 €. In return,
they would like to be mentioned somewhere.
I see no problems with this, given this is an offer we make everyone, so
multiple sponsors can join, and we do not prefer one single corporation.
