To configure the Status plugin:
You can configure how long someone must be idle before they are automatically considered AFK and how long someone must be idle before they are automatically disconnected from the game.
You can disable either or both of these timers by commenting out or removing the line from the configuration file.
You can configure which colors are used to display different status values in the who list and other systems. For example, the following configuration uses red for IC and highlighted blue for OOC.
IC: "%xr" OOC: "%xh%xb"
The game will periodically check for idle players and mark them AFK automatically. There is a cron job to control when this happens. By default it does this every hour. See the Cron Job Tutorial for help if you want to change this or turn it off.
