Add a link to a pm url, inside the pm itself

[fulviods]

I bought this nice plugin http://www.hatnohat.com/hatnohat-sof...-into-threads/ to have threaded pm's !

But the problem is that we can't erase a pm who's inside a thread!
But I found a solution !
If i can access the pm url like http://www.mysite.com/forum/private....pm&pmid=132278
Then i can erase it !

So i simply would like to add a link on bottom of the pm message to his own url.
Si if i'm on the pm id 132278, a link to send me to the complete url.

It should be not difficult, i just dont know where adding this link and retrieve the id of the pm i'm reading.

Any help?? Thanks
