How do I follow a person?

Everyone on the site has a public profile (unless they specify otherwise in their settings). When you see people commenting around the site and you want to follow them, click on their name and then "follow" in their profile. If you want to unfollow them, just go back and hit the "x" in the same spot. 

You can see everyone that you follow and who follows you in "Your Bully Network" in the right hand column.
