A lot of monks here are using various tools
to stay connected to the CB without reloading, and a good
number of them actually do not look at (this part of)
the screen for a while... for example when another window
pops up over it, or a colleague or a boss wonder "how is
the job going?".
I think maybe a /away {on|off}
command could be useful. It would just add a little text
("away", "¤", "A", whatever...) to the right of the nick,
indicating that anybody wanting to talk to this person
should use /msg...
Naturaaly, once you log on again, your status is *not* away.
