%That that people is thinking on what to say or present during the retreat, I would reemphasize the scope of the meeting and organization. The main goals is organize ourselves. The 15 minutes (sharp, no extra time) team effort presentations are dedicated to describe our current commitments. My introduction will include the physics and overview, the 15 minutes talks should clearly list what should we deliver, when we should deliver, what are the challenges and effort needs for final accomplishments. If there is time, the presentation can briefly mention about possible developments for that project once we finish what we promised to our sponsors.
