We have the chance to host BoF (birds of a feather) sessions with up to 70 people. What you will get is a room with a video projector (beamer) and wired Internet connection. To host a BoF just add your reservation to the conference wiki.
Please do not change reservations in the wiki which do not belong to you.
Ask at the registration desk for the key to the room. You will have to leave a pledge, like your passport or drivers license. Besides that using the room is, of course, free.
