My b2evolution Version: Not Entered

Hello everybody,

I would like to send messages deprived between members on b2evo like what week can do in phpBB forum. Not having found a plugin which takes care of this functionality I undertook to develop it. but I find some difficulties. I added a table to DB containing information on messages. Also I wrote a file " _msglist.main.php " (wich allows to show the messages of the linked member) that I aded to the my skin directory.

I have 2 questions therefore:

- are that there is an extension or a plugin b2evo which implémente this functionality and what I missed??

- how insert my file which lists messages in my skin??

Thank you.
