mu-openid-0.91 for WordPress-MU-1.3

mu-openid is a provider or server, allowing your users to use their blogs as OpenIDs.

I’ve just ported WP-OpenID to WPMU, which does what you want — logins and comments with OpenID support. ??

I guess the WP MU users would be happy if you post the good news in their forum and not here ??

I have also done that — but as you’ll see above, the poster was asking about WPMU.

Thanks so much,jdub, your client fits exactly what I needed.
