You create a meeting in Acrobat Connect Enterprise Manager.
If you want to incorporate registration as part of your meeting, you must have the Event Management tab as part of your Acrobat Connect Professional installation; see About meeting registration.
You can create a personal meeting room that you return to repeatedly for your own use, and leave persistent content in the meeting to refer to whenever you need it. When creating a personal meeting room, set the start time of the meeting far enough in the future that the meeting room will be available whenever you need it (for example, you can set the start time as late as 2010 to ensure that the meeting room will be available for the forseeable future).
