Unlike the old forum software, vBulletin somewhat hides the "Report to Moderator" option for posts if you don't know what you're looking for. In the past it was a text link, but with vBulleting it's the little triangle-shaped button with the exclamation point in it down in the toolbar below each post.



Clicking on this triangular-shaped button will take you to a simple message box where you can type in a short description or reason for why you feel the post needed to be reported (i.e. spam, rude behavior, personal attack, for sale or WTB ad outside of the classified boards, etc). Basically if it violates a forum rule it should be reported.



Once you have entered your reason simply click the "Send Report" button and your message and a link to the reported thread will be emailed to the site admin's and the board moderators for that particular board so that one of them can address it accordingly.
