Help identifying a plugin

Hello,

I’m having trouble identifying a plugin (or perhaps is not even a plugin), but can you tell me what plugin outputs the section at the bottom of the post that has the headers: “Did you like this article?” and “Related Posts”, and has a list of bookmarking links, and a list of posts respectively.

Image of the stuff I’m referring to: https://img688.imageshack.us/img688/8361/plugin.png

Thanks!
