This site has no "PM" in place, other that the good old e-mail.
Clicking on a members name will get you to the message index of that person. Clicking on the members name, at the topic of that index page, will get you to that member's profile page, which may or may not list the member's e-mail address. Members can keep their e-mail addresses privite from the general public, if they choose.
By edit: D'oh - Coragyps gives a more direct method!
