If I don't respond to your messages, it's probably because I'm either:
| - In a Steam/non-Steam game that the overlay hates with a passion.
| - Asleep or away from keyboard doing something else.
| - Not in the mood to chat or already busy chatting with a lot of people.

* Some Steam accounts (VAC banned) have been deleted because they had no games and no one logged into them in a long time. But, you might ask, why are they VAC banned if they had no games? That's because they had a game using VAC with Guest passes, free weekends, etc.
