So I wanted to remind everyone of this great feature for link checking!
Basically, all you have to do is check a list of links (one per line) in CSE HTML Validator and it will detect the list and check it.
Here is more information:
See the section at the bottom called "Checking Links or Email Addresses in a Text File (one per line)".
This might also help:
-----------To make it easier for CSE HTML Validator to automatically and reliably detect a list of links (especially a list of email addresses), the first line of a list of links should contain exactly "CSEJOBTYPELINKCHECKTEXTLIST" (without the quotes).
