IntroBar is a nice little web service that lets you build content bars that appear at the top of your site depending on your visitor’s referrer (i.e. the website where they are coming from).

To test things out, I’ve added an Introbar to this site. See it in action by visiting the Facebook Page for mwender.com and clicking on any of the articles posted there. If the article is linking back to this site, you *should* see an Introbar at the top of the page.

Note: during testing I saw the IntroBar in Chrome, but not in Safari. Let me know if you don’t see it.
