If you do not have root rights and the admin does not grant you access to certain files, you can't. This is the whole point about administrative accounts -- to prevent ordinary users to annoy the others.

What you can do is to have a daemon running that periodically checks whether new users log in (who) and have it send messages to them from your account (write, wall)

Thank you for your answer. Can I assume that I have a admin account since writing this script is only for a test condition. I just need to figure out the way to do it. thanks!
