Thank you for contributing a talk in the context of Sailfish OS. Mind that its character should be of a "lightning talk", briefly introducing a topic.
The preferred language is German, but English is fine, too.
Also mind to provide a few minutes for Q&A in the plenum within your 15 minutes time slot. Still there will be sufficient time to continue discussing in a smaller group, later.
Thanks to the FrOSCon organisers for providing a projector and @Thaodan for planning to bring a laptop, so you can simply bring your presentation slides as a PDF on an USB stick or your phone (mind to carry an adapter cable to standard USB with you, then).
You can't submit a talk, because this conference is in the past.
