[Plugin: List Authors] Does not exclude administrator

Very useful — but enabling ‘Exclude administrator’ does not exclude the administrator! Probably because the administrator does not have the username ‘admin’.

Line 165:
$author_where .= ( $author_where ? ‘ AND ‘ : ” ) . “$wpdb->users.user_login <> ‘admin'”;

This plugin would be more useful if the administrator we defined by role rather than login name.
