tip of the day?

[Alvin Thompson]

has anyone thought about adding a 'tip of the day' dialog in ubuntu 
dapper? it could pop up when you log in to gnome or print when you log 
in to the console, and should be trivial to implement.

obviously, the first tip should explain that there's no root password 
and about 'sudo', since that's the most common new user question asked 
on the list by far. subsequent tips could explain other common questions 
or mention cool features that new users may not realize exist (like tab 
completion).

just a thought,
