Masaya gave an overview of the proposed structure of the annual meeting. Working Group Chairs, GCC, ESA and session chairs also provided their thoughts for each breakout session, and the participants discussed the agenda in detail. Then, Philippe kindly provided logistics information. Agenda Item#3 (template for Annual GSICS Report) was canceled due to time constraints, and it will be discussed through gsics-dev mailing list.

The discussion results are reflected in Agenda Item#1, and the following are the highlights. The group agreed that we do not need the second preparatory web meeting, so further discussions on drafting agenda would be done through gsics-dev mailing list.
