-- Message string formats -- Change these if you would like different formatting
--
-- These can be changed to show "~~~#mychannel~~~ <player01> message" instead of "|#mychannel| or any
-- other format you like such as removing the channel name from the main channel, putting channel or
-- player names at the end of the chat message, etc.
--
-- The following parameters are available and can be specified :
-- ${channel_name} name of the channel
-- ${channel_owner} owner of the channel
-- ${channel_password} password to use when joining the channel, used e.g. for invites
-- ${from_player} the player that is sending the message
-- ${to_player} player to which the message is sent, will contain multiple player names
-- e.g. when sending a PM to multiple players
-- ${message} the actual message that is to be sent
-- ${time} the current time in 24 hour format, as returned from os.date("%X")
