I just had a couple questions:
1) is it fully WP 3 compatible? The plugin page says up to 2.9.2.
2) Does it work fine with plugins like Janrain Engage (RPX) that allows users to sign up via various social networking options? I'd like to have a private site for family, however I want it to be dead-simple to sign up/in or people won't use it. Can this plugin be used with Janrain Engage?
