Subject in HREF for PM?

[palbanes]

Is it possible to have a pre-defined subject parsed into the pm action using href?

for example, something like:

http://www.kctennisplayers.com/index.php?action=pm;sa=send;u=1;subject=Child%Forum%Request [nofollow]

Apologies for the lack of a reply.
I had a look into this. By default SMF prevents passing variables in the url for security reasons.
