Suggested Action Group Conference Call protocol:

1.  Hand-raising in the chat room. This encourages full group participation in the call.
2.  Post notes on Wiki and GoogleGroups, for final inclusion in the meeting minutes.
3.  Schedule conference calls in advance and on a regular basis.  Google Calendar and TimeandDate.com may be helpful scheduling tools.
4.  Identify yourself by name before speaking.
5.  Mute microphone when not speaking.
6.  If the proposer of the agenda item is not present, the idea doesn't need to be discussed, and should be tabled for the following call.
7.  Individual agenda items should also list 'presenter' or 'proposer' name.

In addition, it may be helpful for each Action Group to nominate an official call coordinator.
