The *Main Tracks* are two simultaneous lectures given in the two biggest rooms giving a seat to 550 and 1400 visitors. They tend to host lectures for a broader audience than the specialized Developer Rooms. .... You can send in your abstract if you meet the following conditions: * The subject is about free or open source software development. * The proposed lecture is technical. Our visitors do not come to FOSDEM for a marketing talk or a simple overview of the features of your product. * A Main Track talk is given by one person, who is a developer of the project. * By sending in your abstract you acknowledge that you keep the dates of 6-7 Feburary 2010 free in case your proposal has been selected. * The travel expenses and hotel bookings of main track speakers are covered by FOSDEM. Speakers are kindly asked to book their travel themselves while FOSDEM manages the hotel. Bringing your partner is encouraged but his/her costs are not covered by FOSDEM. (except the hotel) * All Main Track talks will be recorded. The recordings and slides will be made available freely, shortly after the event. ....
