A "half moon" at facebook chatting..?

what does it moon when in the chatting box there is a half moon by the name, i know a green circle is that they are online but what about the other thing, the half or forth of a moon that mean theya re away? or just went offline ?

thnx :D


It means they are idle.


They are online but have been "away" for 15 minutes. As soon as you click on something on facebook you are back and the half-moon will return to the green circle. If they are offline, you won't see their name at all.
