Is there a way to capture the emails entered in comments section into aweber list

Is there a way to capture the emails which are entered while commenting on the wordpress blog and adding them to aweber list?

Better is there a plugin which could开发者_开发百科 do the same?

Thanks Prady

You could run a MySQL query on the wp_comments table like...

SELECT DISTINCT comment_author_email FROM `wp_comments`;

...But please realize that unless your commenters have specifically opted in and are aware that they're going to be added to a list, they may get really annoyed as what you're doing is tantamount to spam. :|
