Did you know that people get redirected to a community login page instead of a 404 redirect when they hit archived knowledge articles? Yea, I know! This is a frustrating experience for our community members. Please vote up @Mirna Lessinger 's idea to change this negative experience and have archived pages redirect to 404 pages instead. We have a 404 page that links back to our community search, so that's a MUCH better experience than hitting a login page, only to be told the page is invalid anyways. Thank you!
