Just a quick reminder for those who are not familiar with the WDG Validator. It is a recommended validation tool by the W3C. What's neat about the WDG Validation Tool is that you can validate up to 100 pages at a time. You can also narrow your validation routine by entering a direct path to a sub-directory and targeting those pages only.

The validator does obey the robots.txt protocol so it will not validate anything that is disallowed in the robots.txt file.
