I'm like one of these people who will drop a "hey" to people if they're busy or away but if they don't reply thats cool I mean they're not exactly set to online. I get annoyed with people if they message me when I'm set to busy because that means I'm either watching a movie on my laptop (headphones, very useful late at night when people are liable to go nutty) or I'm truly busy/doing something full screen because if I can sit there and have a convo with people I sit there and have msn signed in as online. I also make a comment in my personal message when busy/full screen like "playing guildwars, you may speak but no reply until I close the game down :P" or "watching movie" and even better "sorry guys, really damn busy atm give me an hour or two please" since I only have the "show what I'm listening to" on when online as online I find it annoying people say "oh sorry didn't notice" what little red and white "no entry" road sign icon didn't give it away? or the personal message that came up when you highlighted my name with your mouse? geez
