Panaghiotisadam and windwhistle put together a really nifty little code for protesting SOPA on WordPress.com blogs.
- Go to your Dashboard.
- Hover your mouse over Appearance and click on Widgets.
- Drag a Text widget to your Widget Sidebar and paste the following code into it.
<div align="center" style="position:fixed;width:100%;height:100%;top:0;right:0;background-color:#000;-moz-opacity:0.8;opacity:.80;filter:alpha(opacity=80);text-align:center;font-size:800%;font-weight:bold;padding-top:300px;"><a style="color:#fff;" href="http://americancensorship.org/" target="_blank">Stop SOPA</a></div> - Feel free to edit the text and the links if you get this html stuff and GO TO IT.

Thank you! This is really slick. I’m blacking out first thing in the AM tomorrow with this thing. I’m adding a link to you to my Facebook account – don’t get too excited, I have about 30 “friends” so this won’t be bringing the server to its knees, but every little bit helps in the fight against censorship, right?
