At the end of the tutorial mission, it says something like "Everyone starts out in channel 1, but there is 30-second delay on communication to keep the noise down... a lot of people talk on channel 100, type /join channel 100 or /leave channel 100 if you wish"

...with the last update, it automatically starts the player out in channel 100, and I also believe the 30 second delay is obselete. Not a huge issue, just few lines of text that might need to be changed to avoid confusion.
