The conference call format went well. It gave everyone who usually doesn't get to network with each other a chance to meet by connecting over the phone. None of the people on the call tonight usually end up attending our regular meetings because of distance. Most of the local folks opted for a meeting next week instead.
Although we moved the networking opportunity to on the phone instead of making people drive on the predicted ice, I wasn't sure how it would turn out. Now we've had two of these calls and they seem to be flowing. It may be worth doing again regardless of weather.
