I seen it all the time, still no idea, in trades it says user Idle(3) or (123), or any other # what does it mean?
That they were recently on. I'm not sure what the number represents though.
FINALLY GOT THE 15K WARDROBE DONE!!!!! Next up gutting and selling it.
It's how many seconds the site hasn't detected any activity from the user - I assume it resets anytime the person visits/refreshes a page. So Idle(120) = two minutes with no sign that that user is on Idle(1200) = twenty minutes of nothing
I have no idea how long it takes until it switches to "offline" though.
