Features:
Every user can decide if he wants to receive messages or not which means he can activate or deactivate the service.
There are three mail boxes: inbox, outbox and savebox.
The inbox contains the messages you received.
The outbox contains unread messages you sent to another user. As long as the other user hasn't read the message you can delete it.
The savebox contains messages you've saved. When sending a new PM you can put a copy in the savebox or you can move a PM from your inbox to the savebox.
You can send a new PM to every user who has activated the service. Or you can send a PM by clicking the "Reply" button.
Admins can send PMs to all 4 user groups. If a member of a selected group didn't activate the service the message will be sent by email to this member if there is an email address available.
You can check out everything on the demo page: http://english.cutenews.ru/forum/index. ... rum_link=1
Update:
I added the possibility to get a mail on new messages. (See installation instructions.)
Installation:
1. To activate mail on new messages open private-messaging.php and find the last function at the end of the file. Set $mail_on_new_pm to true and change the mail text to your needs.
2. Just copy private-messaging.php to the plugins folder and private-messaging.ini to the inc/lang/en/plugins folder. Then activate it in the admin panel.
Enjoy!
