I just got an email regarding next weeks CodeMash:
We have created a google group for CodeMash attendees. If you are interested in discussing CodeMash before, during, or after the event, please join!
This will also be a good place for finding opportunities for carpooling to CodeMash with others from your area, and for ride-sharing from the airport, if you are flying in.
You can subscribe to get email, or with a gmail account, you can read on the web.
