I run a forum mainly for teenagers and feel that I have a moral obligation to keep pedophiles off of my board, so I read my users PMs regularly as this is the medium that Pedophiles seem to like to make their attack on. I make it clear to my users in the TOS that all forms of communication on my website are monitored and if any foul play is going on, we'll find out.
Anyways, yes; this is the mod I use:

It's a big buggy but it does the trick.
