I was at the page: http://developer.redhat.com/bugzilla/show_bug.cgi?id=3487 and hit "home" and got a 404 error. The url was index.phtml and so I tried index.html and that didn't work either.
RHCN no longer exists so closing this bug.
RHCN has been discontinued and therefore this bug report is being closed. If you have any questions about why this bug should not have been closed please direct to bugzilla-owner. Sorry for any inconvenience.
