This plugin implements a set of template tags for identifying invalid link URLs within entries.
If your site has been around for a while, a few or many of the pages you've linked to in the past may have ceased to exist or moved to new locations. Also, if you tend to link to a large number of pages, you might not be in the habit of clicking on each and every link to check it, so some URLs might not have been valid in the first place. The CheckLinks plugin tries to access all the URLs linked to in your entries (or a subset of your entries), and lets you display a list of the ones it can't successfully access.
