First, use w(1) to see who is currently logged in, and get some idea of what they're up to.
w(1) doesn't list all users.
You can use write(1) to send them a message, but this can easily be overlooked, so don't be offended if you don't get an answer!
But if it keeps others from screwing up my screen with direct write(1) to it, I'm starting to like that w(1) glitch that keeps (not only) my presence secret.
`man 1 mesg` helps to disallow write(1).
You can also use finger(1) to get a sort of MotD from any user who has set a .plan and .profile file.
`.project`.
That's all I have off the top of my head, but if anyone else thinks of some interesting or weird things that can be done when multiple users are logged into the same computer, please share them!
Look thru `ps`, `ps aux` and `top` for getting an idea what's happening on the system.
If you want to get in touch with others please try less invasive methods than write(1) first. Maybe mail, irc, ...
