Hello NYC COF. Since I've been emailing with Adrian a bit, I thought it best I come into the group and start a thread so that I could answer any quesions that you may have. Also, feel free to check out our FAQ.
In the group you can use the dashboard in the group to post a message to the entire group, upload multimedia or to blog within the group. There is also an events calendar where you can list events. And then there is the discussion tool that I am using right now to send out this update.
