The private messaging should include following functions:
1) inbox, 2) sent box, 3) Draft, 4) Trash, 5) compose a message (file upload) / delete message / reply message, 6) move to, 7) search

Customize existing Yii framework extensions (e.g., http://www.yiiframework.com/extension/private-messaging/)
