TY Scott--i assumed that what was meant --but i had never seen a post on here about it.Or i might have missed it.Ty for the reply.
It's a general guideline, but doesn't always mean they will be available if green. Most days I play a game in the morning before leaving for work and then just leave the app open. So it will show me as green and available (which technically I guess I am) but I will not be in front of the game ready to play. Also you can set your status to offline and you won't show up in Friends list even if you are online and ready to play.
