Is MSN an OpenID provider? If so, do you know what the URLs look like?
I'm trying to add MSN to the list of providers with special buttons I already have for logging in to a web sit.

Microsoft has an OpenID service attached to Windows Live ID that is in beta at the moment. Not every Windows Live ID user seems to be able to use it.
To use it, users have to create an OpenID alias, where they will be provided an OpenID URL.
No. MSN does not offer OpenID to its members.
Windows Live ID Added to RPX. Have their plugin enabled in my WordPress blog, and I added Live ID as one of the sign-in options. Just tested it out, and it works for my Live Id :)
