Dear Media Fragmenters,

Apologies for this late notice. Please, find below the agenda for this 
week telecon:
http://www.timeanddate.com/worldclock/fixedtime.html?day=07&month=10&year=2009&hour=09&min=00&sec=0&p1=0

Silvia, beware the telecon is one hour later for you (i.e. 20:00 PM
Sydney time).

I have included in the agenda a proposal for publishing our 2 documents 
as WD. My actions are still pending but I will try to do my best to 
complete them before the telecon. Apologies once more for being the 
blocker. Time is currently crazy with EU proposal writing.

Conrad will be our scribe (Yves is on deck).
Actions opened:

Best regards.

   Erik & RaphaŽl
