XML Limit 25 authors

Hi,

problem is this:

$sql = “SELECT DISTINCT
u.ID,
u.user_nicename,
MAX(p.post_modified_gmt) AS last_post
FROM
{$wpdb->users} u,
{$wpdb->posts} p
WHERE
p.post_author = u.ID
AND p.post_status = ‘publish’
AND p.post_type IN(‘” . implode(“‘,'”, array_map(‘esc_sql’, $enabledPostTypes)) . “‘)
AND p.post_password = ”
GROUP BY
u.ID,
u.user_nicename”;

Only show authors with publish posts.
