How do a see what a user is doing (input/output to screen)

[James Gardiner [hunter]]

I have just started a Public access UNIX system in Melbourne
Australia.  I am learning alot as UNIX admin is new to me
(and nothing like you expect)
Anyway,  I was just wondering if there was a way to see what
my USERS are doing.  Ie like a PC bbs, where what the system sends to 
the user and what he types, is desplayed on a screen for me to read.
I read some where a while back that on IBM UNIX machines, there
was a way to make a mirrored tty device that you could read?
