This is a tool for players in game to summon you from your real life, hence the name.
Go AFK while on standby without worrying!!
However, this mod will not stop you from being logged out due to inactivity.

It works by changing your AFK message to one of your choosing, attaching a keyword (also of your choosing) to the end of it.
When someone sends you a tell and discovers you are AFK, your AFK message will inform them of the keyword to send.
If they send a tell with the keyword, a sound will play alerting you to return to your desk (turn your speakers up if you cannot hear it from where you are going to be, you can sample the volume by changing the "Summon Sound" drop-down in the configuration (/irls or /IRLSummon or Mainmenu, Interface, Addons Tab).
There is also an option to mute game sound while you are afk so you can turn up your speakers without other sounds playing (Doomwalker for example).
As of v1.2 you have the option of monitoring guild and chat channels for keywords (character's name by default). A whisper is then sent asking the player if they need your assistance (they could then respond yes or use the normal keyword).
As of v1.3 you have the option of recieving a notification before you are logged out due to inactivity, this is a seperate (selectable) sound from one used to summon you.

Code from CCTimer was used for the configuration and sound sending, though there is not much of it left.
