I just read about OpenID (maybe I'm a little behind), but it's not working innately on my wordpress domain. I have found the Scatmania hack, and while it says I need WPv1.5, it doesn't say whether it's 1.5 exclusively (as in not 2.x) or whether that means anything above 1.5. Last week someone said how great it worked, but that still doesn't answer whether they had an older version still up.
Is there a better answer yet, than hacking up my WP files? Can anyone tell me if they've had success with the Scat-hack on WPv2.x?
