First lemme throw questions:
How many of you "afk" while keep logging the game?
How many of you "afk" while keep logging the game and turn your AC on?
How many of you think how many electric bill will you have next month?

Because like Ben Parker said, "Behind a great power, lie a great electric bill"

Thus, I'm suggesting to Dev an auto log feature, that will kick you out (from the game) if you being iddle in a certain amount of time
Definition of iddle would be:
- Standing/sitting/hecking the bed and not doing anything, not even chat or checking menu
- I would put "while crafting or gathering" but that would be too much I think

Other feature:
- The auto log out could have/use a timer (that could be set by player)
- If the player/client is idling while waiting for command input (gather/craft), the game will throw a message box "are you sure you want to log out". I havent decide whether this will be just a message box (you will still log out) or this will need the player input (there will be yes/no option)

And, GO!
