I've been waiting for someone else to post about this, but that's no way to get anything done, so:
Is anyone else in the DC metro area interested in doing Drupal co-working days? I know I'm not the only one around here that works from home.
I think that the first thing we need to do is gauge interest and get a ballpark number of people who might attend, so that we can then find a suitable space for us. To that end, go ahead and comment here if you're into it, even if you just say +1.
