Amir Aharoni is planning two developer days just before this year's Wikimania -- August 2nd and 3rd in Haifa, Israel. If you're planning on being there, add your name!

This developers' meeting is an opportunity for Wikimedia's software developers to come together, test software in diverse languages and on diverse devices, squash bugs and write awesome new features.
It's a perfect opportunity to work on right-to-left language support, of course, but what else would you like to work on? Please add your ideas. This'll help recruit attendees, and help us knock out any dependencies in the eight weeks between now and the hackfest.
