WordPress does not allow your users to communicate with each other. Some forum plugins can add this functionnality but are quite heavy, do other things and updates might not be focussed on improving the messaging features. This is why User Messages is born: a plugin to facilitate communication between your users.
How About Getting a Demonstration?
Feeling shy? Afraid that the plugin does not do what you want. Well maybe you could first download the latest free version of the plugin on the WordPress Plugin Repository and start using it a bit. This will give you a good idea of what the plugin is and how it works. The commercial version has been rewritten to improve this first prototype and make it greater.
