Seems like you solved this. If so, please consider posting how you resolved it. Thanks.
yes please, I’d like to know how to make the email field optional.
Well I haven’t tried this, but you could probably remove the previously entered urls by running an SQL query in phpMyAdmin. Something along the lines of:
UPDATE wp_comments SET comment_author_url='' WHERE comment_author_url='%'
No need to do that, mylagoon. Just edit the theme’s comments.php and don’t use tags that spit out the URL in the comment loop. Use $comment->comment_author if need be.
Then down in the form, delete the URL input field and make the e-mail one hidden with a default value of like fake@nieuwszicht.com.
Problem solved.
And yes, I realize that there is an option in the admin area called “Comment author must fill out name and e-mail”, but if that’s unchecked, I think posters can post without a nick filled in and that’s not desirable, at least to me.
