Footer On Homepage

This (relatively simple) plugin gives site owners an opportunity to stuff some SEO-friendly text into the homepage (and only the homepage) of their site. It will initially display only as a link, but when the visitor clicks the link, the full specified text displays right there in the footer for the user to see.

It is also a great example of how to use wp_editor() [new in 3.3] and still be backwards-compatible.

The admin side, as of v1.0.1, has a text box for you to specify your own CSS stylings of the footer div. So go ahead and make it look however you like!
