Dear Media Fragmenters,

Please, find below the agenda for this week telecon 
http://www.timeanddate.com/worldclock/fixedtime.html?day=03&month=03&year=2010&hour=10&min=00&sec=0&p1=0
Actions opened: 
http://www.w3.org/2008/WebVideo/Fragments/tracker/actions/open

This is our last telecon before the F2F meeting. We need to have most of 
our actions done before the F2F so we can discuss issues. We will focus 
the discussion on:
   - all the ACTIONS you would have _done_ ;-) we have way too many open!
   - good preparation of the F2F: add your topic!
   - there are a lot of small actions on TC, I'm also worried on their 
progress.
Best regards.

Erik & RaphaŽl
