Unable to PM someone?

This is kind of a dumb question but I created an account mainly to PM someone and was greeted by this message:

How exactly should I “participate more”?

I don’t think you can PM someone until your first post has been approved by the moderators. (We filter out spambots by looking at the first post.)

Now you’ve had your first post approved, so I think you should be able to PM someone–let us know if it doesn’t work!
