I'm looking for a way to create a whitelist of comment authors.
NOTE: We do not do user registration on our site and we don't want to add this. We want to continue to allow people to comment by entering in their name/email/website without having to login or register.
Thus, I'd like to be able to manually put together a whitelist of approved combinations (e.g. comment author name + comment author email + comment author URL if applicable).
Even better, would be a way to add a user to the whitelist directly from the archive of approved comments.
I realize we could use the "Comment author must have a previously approved comment" option, but I would like a more robust solution than this.
