 Moderator/video switch options:
 'M' : member is a "moderator". When a moderator quits, all members are kicked and the conference is disabled.
 'S' : member accepts VAD controlled video switching.  Do not use with 'X'.
+'z' : member can "linger". When the member is currently transmitting video and becomes silent and nobody else is speaking, we stay on it.
+'o' : enable special behavior when in 1 and 2 member situation (one on one video). The conference observes the 'o' status of the last 
+      member to join it
+'F' : force switch mode: if the member is talking, force a switch to it even when there is no video
 
 Miscellaneous:
 't' : member accepts text based control messages.  The messages are described in a separate document
