AFK Button

From CSMWiki

During the gameplay, it often happens that persons are ingame but not at their computer because they are AFK for lunch or just off for some biological needs or talking to other people via skype, phone and so on. Or they are in an other channel for an important discussion.

Then often it happens that other players want to chat/talk to the person who is away. Then they are asking repeatingly "is XYZ on", "when will he/she be back?", "can somebody call him/her here?". This can be very annoying to the other channel members.

A little graphical implementation, for example a small red bullet, in front of the name (or the name written in red), would clean up this situation very easily. Perhaps this can be extended by a little text below the name or as an info overlay when the mouse is over, which may present a custom message like: "For lunch - back in 30 min at 13:00 eve time".

The icon for it can be positioned at the left side of the top right buttons at the chat window. When you click on it, a popup window opens where the user can type a reason and define the duration of his/her absence.
