Hi Pierre, The EUROSHA volounteers here are available if you want to contact them at [email protected] or i'm on IRC too (xivk) if you want to contact the EUROSHA people that way.
Coordinating this is indeed very important but i guess everybody here is just eager to do some work sitting on all this data! :-) Met vriendelijke groeten, Best regards, Ben Abelshausen [email protected] http://twitter.com/xivk On Tue, Mar 26, 2013 at 4:49 PM, Pierre Béland <[email protected]> wrote: > Ben > > For the current Activation in DR Congo, I coordinate this with Claire > Halleux.
