I was invited by Mozilla to attend MozCamp 2011 in Berlin.
I've worked a lot lately on Narro improvements because the Narro instance hosted on Mozilla servers is used by more locales and because I'm not getting any younger and wanted to do more and faster. If you're reading this, attending too and got some questions, don't hesitate to contact me.
It's been 4 years since my first meeting of this type and I can say that after each meeting I get back with a lot of ideas and with batteries recharged for what gets me to these meetings in the first place: cotributing to open source software development.
Have you tried that yet ?
