I wondered if this forum could support OpenID? http://phpbbopenid.com/viewtopic.php?f=2&t=2
Might also be interesting for Bugzilla. https://wiki.mozilla.org/Bugzilla:OpenID_Auth_Plugin
Apart from that, the little discrepancy between forums.gentoo.org (/ .kde.org / .ubuntu.com / .amd.com / .nvidia.com and more) and forum.sabayonlinux.org is also constantly getting me - could there be a redirect from forums to forum on the server, or vice versa?
