AutoCopy Automatic Copyright
AutoCopy automatically updates your site copyright notice every year. You can specify any copyright text you want, AutoCopy will replace "(c)" with the current year or a range of years. This makes it easy to embed a copyright notice in your footer text (we use it, take a look).
You will only have to configure AutoCopy once. If the site was started in 2010, put that in as the start year. AutoCopy is so mind-numbingly brilliant that it compares the current year to the start year and writes ©2010 instead of ©2010-2010. Then in 2011 it will write ©2010-2011, without any manual intervention. Nobel Prize nominations are surely forthcoming.
