Chris sent me email today about their user group and the use of LiveMeeting to broaden their reach. You can get details from their site - http://livemeetinguser.org/
The Live Meeting User Group is a collaboration forum primarily aimed for Live Meeting users, resellers, developers, and partners. The aim of the User Group is an occasional social evening in London or Reading, combined with an online outlet for collaboration and support with regular Live Meeting webcasts
I will be interested to see if they end up discussing the aspect of Office Communications Server 2007 on-premise meetings as well.
