SevenCubed, thank you for sharing this info. I read and reread your post. I may be acting dumb, but I can still see 4 links to my site even if my site doesn't pass validation test. Should one then take the extra mile of validating the site or simply stick a link to the validation page from somewhere and get it indexed?
When I append & with & on a valid URL, I get the message "No task specified. Unicorn used its default task: "General Conformance Check"." Why should & be appended with AMP;?
