Here is my solution.

I used the script provided by that website (local copy, because I expect them to be hit hard & didn't want it to slow down my site). And I closed my site using this message.

Feel free to edit and change as you like
(you'll need to change the link and the name for your site anyways)

Attached is the local copy of the script.

<script type="text/javascript" src="//www.YOUR-DOMAIN/sopablackout.js"></script>

<p>Today, YOUR SITE NAME has joined Wikipedia, Tucows, Reddit, Boning Boning<br />
and many others sites to temporary blackout our community for 24 hours <br />
to help bring aware the threats of SOPA and Protect IP (PIPA)<br /> </p>
<p>What is SOPA and Protect IP (PIPA) ?<p>
<p>I feel the video above does a fine job of explaining this.<br />
But basically The United States Government is trying to pass a bill that could<br /><b>censor everyone on The Internet</b>.<br /><br />
And it would affect you even if you're <b>NOT</b> an American Citizen or even if the website you try to visit is <b>NOT</b> an American website (we're not).</p>
