Let's keep the momentum going from our successful birthday party! Since we didn't have time to do hands-on editing there, this one we'd like to focus on using the iD editor. No experience necessary. Bring your laptops!
In the spirit of mapping-what-you-know, it would help to take a look at the OSM map beforehand around where you live and hang out to see what's there and what's missing. (e.g. supermarkets and shops, restaurants and bars). Jotting down names and locations on paper is really helpful!
Also, Clifford is planning a Seattle bid for the 2015 State-of-the-Map US Conference. With the number of active FOSS/GIS people in this area, we could pull this off. We'll be discussing it, so bring your ideas!
