In-site private messaging php script

[Ozz]

I want to add a private messaging facility for my members.
After some search I found this script:
http://pmsys.sourceforge.net/index.php
But its quite compilicated. I need a more simple one.
An inbox and sentbox and send message ability is enough.
I use MySql for database.
I want to do this with adding a table to my database.

What do you suggest?
Any ready-to-run scripts do you know?

Thanks by now...

I dont know any pre-written scripts but its simple enough to code one yourself. All you need is a table in your DB with a row for each message containing the message text, message sender, message recipient, date sent and optionally, columns saying whether the message has been read or replied to.

A script should also be regularly run to delete any messages that are over x number of days old.
