Cross browser compatibility test site

BROWSERSHOTS.ORG
I use this site everytime i check my design. You can choose from a lot of browsers too. This site is amazing. 

How the site works:
Browsershots makes screenshots of your web design in different browsers. It is a free open-source online service created by Johann C. Rocholl. When you submit your web address, it will be added to the job queue. A number of distributed computers will open your website in their browser. Then they will make screenshots and upload them to the central server where you can see the result.
