[atlas] Promote the use of IRC

Hi all, Yesterday, I've started a discussion in the member list about promoting the use of IRC instead of Mail List for some kind of discussions, chit chat, etc. Not much members answered, but all who did said yes. The goal is to have, at least, one channel per mail list, but not limited to only that. For this list, an #atlas channel will be created and administrated by the WG Chairs. We want to use the actual RIPE IRC Server plus Network Services and some more irc servers linked to the Ripe one. What do you think? Regards, --Daniel
