Hey everybody... I ran into an issue recently with a form on a web site. Since we use WordPress to offer subscriber accounts, our wp_users table has > 60,000 entries. The problem is that when you go to edit a form (which accesses form_detail.php), the page either takes 15 minutes to load or you get a jquery error (in FireFox) because there is a dropdown menu . To get around this, I added another variable to the dropdown_users() array on line 508 of form_detail to include just the admin:
<?php wp_dropdown_users(array('name' => 'field_post_author','include' => '1')) ?>
What would be awesome in the future would be, for those of us who have much larger wp_user tables, either an option to limit these users by permission level or specify certain users only who would show up in this drop-down list.
