I fully support the protest against SOPA/PIPA but if you really need to access wikipedia you can disable the javascript in your browser<p>1. for CHROME preference->under the hood->Do not allow any site to run JavaScript
2. for SAFARI preference->security->uncheck Enable javascript
3. for FF preference->content->uncheck Enable javascript
4. for IE I didn't care enough to check it:p
Even easier — here’s a userscript that removes the SOPA overlay on English Wikipedia: <a href="https://gist.github.com/1631807" rel="nofollow">https://gist.github.com/1631807</a>
