We've already asked you to help compile a list of open source events and conferences. Now we've got a map. What's missing? Leave a comment with the event name, location for 2012, and URL. Anything you mention here, we'll also add to the list in our Resources section. Feel free to share this map, download the data, and reuse it.
Tip: Big box that says "Layers" in the way of the map? Click the small green double arrows at the top left to hide this menu.
