FOSS4G2019 Q&A Sevilla

Questions Till Adams:
 * Do you expect, that you can attract your supporting organisations also to sponsor the event?
 * You expect 80% of the attendees to pay the registration fee. I am a friend of a very careful calculation, nevertheless I'd like to ask, who you expect not to pay the fee - at least 20% of expected 1200 attendees are 240 people, that receive a free ticket?
 * There was a big discussion about how we can open the conference for as many attendees as possible. Of course, this also is a function of the whole package price (travel, accommodation, conference fee,). Could you please line out, what your plans are in order to make a travel to FOSS4G 2019 possible for as many people (especially students, people from 3rd-world countries) as possible?
