Oh, and here's an example of a 410 Gone page from my classifieds:
http://www.fordf150.net/classifieds/...php/product/26
and a good 200 OK page from my classifieds:
2003 F-150 Blue Supercab FX4 - Ford F150 Classifieds
Notice the user doesn't even know what a 410 is (there's no indication to them, which is good) but check the status codes on the two pages here:
Check Server Headers Tool - HTTP Status Codes Checker
As I said, I'm not considering this a "bug", more of a "suggestion", that's why it's in the suggestion forum.
