9. Meetings, Feb. 05 - Jan. 06 It is planned to have a general meeting of all participants and contributors of Task 11 in February 2005 (the date is still not fixed). During this meeting, different working groups will be formed. Two other meetings of all participants and contributors are planned (after 6 months and after 12 months) where the results of the different working groups as well as deliverables and reports will be presented. Moreover, if necessary, the members of different working groups can meet more frequently.
