# Map Comment Authors?

 * Post authors are mapped from Blogger to WordPress when using this plugin. Is 
   it possible to do the same for comment authors? The user_id for all comments 
   in the wp_comments table just seems to get set to 0, so the comments don’t get
   associated with WordPress users.

 * Blogger does not supply the email addresses when you port the users across, they
   are all “noreply@blogger.com”, so it is a bit difficult to identify all the comments
   linked to a specific commenter.
 * It might be able to match the users on the username and/or website but I’m thinking
   that for large sites the numbers could be excessively large.
 * If you just want to fix the gravatars it’s possible to do that with a series 
   of update queries, I use something like the following to fix up the missing emails
   on the comments I’ve made myself.
 *     ```
       update wp_comments set comment_author_email = 'myemail@server.com'
       where comment_author = 'Andy from Workshopshed'
       ```
   
 * You could do something similar to set the user_ids.
