I've seen links in signatures that say something along the lines of "click here and get me some tc" and they take you to a page with a small picture/video on the left and the banner on the main page of toribash website. I was wondering what this does, and how do I get one.

If you can't understand this, I'll edit it for clarity.

EDIT: For example, in Daxx777 signature two posts above mine.
