Typing the command "afk" puts a flag (AFK) in your title which lets
all know you're not currently available. It also sends a similar message
to anybody who tries to tell to you. AFK stands for "Away from
Keyboard". The flag is automatically removed when you enter your 
next command. You can also add up to 8 characters after typing AFK
for a reasoning behing your unavailablitity, for example (AFK:Phone 8m)
