This is very, very cool. The EveryDayMatters group has set up a map which features the locations of every member who enrolls. Try it out and add yourself. It will be very helpful for planning future Sketchcrawls and events and it's a great way to get to know the gang. You can chat, even put up a portrait.
Also, don't forget to A) join the EDM group and B) add yourself to the members' database.
