What is Comm?
The communication interface allows a chair to send messages directly to the Chair Announcer In-World object, to be announced to the groups via a METAbolt logged in avie. This eliminates the difficulties encountered when trying to listen to chat designed for human consumption and parse it into suitable material for announcing.
If you are a chair developer you can register your chat codes and a version of the Comm plug-in script will be made available to you and will be included with future versions of the Chair Announcer for retro-fitting to your chairs.
