I'm only on for about 10-15 mins at a time before I have to go. Yesterday I myself was only online for about 45 mins total, and constantly having to make food, do homework, feed the dog, or take my little brother to Basketball practice. Being AFK about 50% of the time is hardly conductive to a succesfull sortie.
I have it set to "stay logged in". I think that whenever someone is on the computer, it says that I'm online, but not sure on that.
