Passing PM Title In Text Link

[EricGT]

Hello. I am wondering if there is a way to pass a title for a new private message in a text link.

Here is a typical text link to start a new PM for a specific member: http://mysite.com/forums/private.php?do=newpm&u=userid

Is it possible to include a title for that new PM like this: http://mysite.com/forums/private.php?do=newpm&u=userid&pmtitlevariable=PMTitle , where 'pmtitlevariable' is an existing variable in the vB PM system designed to accept this sort of input? If so, what is the name of the variable? Thanks for the help. Eric
