There are many plugins and WP features that take advantage of the email address of its commenters, such as Gravatars. Would it be possible for WP-OpenID to attach the email address of a confirmed OpenID user? There are two options to this feature request:
a, the ideal solution:
– Get the email address of all OpenID users and add it into the comment_author_email field of the database.
b, the less-than-ideal, but still okay solution:
– Any user that has a WordPress account at that certain website will have their email address added to any comment made with the openid they have associated with their wordpress account.
Just a suggestion that would help sustain many commenting plugins such as Subscribe to Comments, Gravatar, Retaggr, and many many more.
