This is my Comments config:
private static $default_config = array(
'require_login' => false, // boolean, whether a user needs to login
'required_permission' => false, // required permission to comment (or array of permissions)
'include_js' => true, // Enhance operation by ajax behaviour on moderation links
'use_gravatar' => true, // set to true to show gravatar icons,
'gravatar_size' => 80, // size of gravatar in pixels. This is the same as the standard default
'show_comments_when_disabled' => false, // when comments are disabled should we show older comments (if available)
'order_comments_by' => "\"Created\" ASC",
'comments_per_page' => 10,
'comments_holder_id' => "comments-holder", // id for the comments holder
'comment_permalink_prefix' => "comment-", // id prefix for each comment. If needed make this different
'require_moderation' => true,
'html_allowed' => true, // allow for sanitized HTML in comments
'html_allowed_elements' => array('a', 'img', 'i', 'b'),
'use_preview' => false, // preview formatted comment (when allowing HTML). Requires include_js=true
);
