Is there a plugin or a way to make the comment submitter to validate the email address provided before the comment is shown?
Logged in guests won't need this routine, but guest posters should be made to go through this routine so that they do not input bogus email addresses when they post.
I see that engadget.com uses this and it's very effective.
I'm not looking for this to fight spam (there are alot of plugins that do those stuffs). I just want something that will make guest posters input valid emails. I think this is the least they can do as a guest poster. If they feel it's too troublesome, they can register. I really don't like comments with false emails such as firstname.lastname@example.org.
Any help would be appreciated.
