Where to find a PM system

[oiwio]

Anyone know where I can find a very simple, secure, and easy to manipulate private message system or script?

Many CMS have an inbuilt PM system.Or the particular module can be added.

Which CMS(content management system like joomla e107 etc....) do you have?


i just googled and found
http://pmsys.sourceforge.net/download.php i am not sure about the working of the script.
