I want to suggest a custom 404-error-page on every Gentoo.org related site, where you can easily send a feedback to the wemaster, which includes which link you had tried to open and where you came from. I think userfeedback would raise as not everybody feels the need to open a bug only to notify the wemaster about a broken link on www.gentoo.org. Reproducible: Always Steps to Reproduce:
if we do offer a custom 404 page, it would still direct people to bugzilla. It's easy to overlook issues via email...bugzilla is our preferred (and only) issue tracking system. we may still offer a custom 404 page under the redesign project. closing this as later for now.
