I'm in Prague right now at Mozilla Camp Europe 2009, where the whole European Mozilla community has gathered. I'm looking forward to meet most of our European localizers and drink some beers with them :)
I'll also be part of the Thunderbird talk that Ludovic Hirlimann is doing tomorrow about Thunderbird 3.
On a whole different topic: 17 locales have already translated all their strings for Thunderbird 3. More will hopefully follow soon. Very exciting!
