Blackout your blog.
The list of plug-ins that will blackout your blog for the day and automatically return it to normal is none-too-short. I installed the SOPA Blackout Plugin to display a splash page for my visitors on the 18th. The settings allow me to decide if I want visitors to be able to view the site at all — and I do. Simple Stop SOPA will take your site offline between the ours of 8AM and 8PM on the 18th.
Redirect your blog.
If you don’t mind losing hits and possibly confusing or frustrating your visitors, consider the Stop SOPA and PIPA Plugin to redirect your visitors to the official Stop SOPA website where they can cast a vote.
Display a ribbon.
Perhaps the least obtrusive plug-in, the Stop SOPA Ribon simply displays a diagonal banner on the top corner of your blog. If you can’t afford to take your website down because of business/advertisement/financial obligations, this is the one for you. Your readers can click the ribbon to go to the American Censorship site to learn more about why SOPA sucks.
Put up a widget.
Have a little room in your sidebar or widget? Host a widget that helps to increase awareness about SOPA for the day of January 18th.
