Same here, does not work, because there exist no phrases as are in the php file, for ex. "GARS_addon_member_top_comments" I think. Also there's no GARS_addon_member_top template as requested in the php file.
PHP Code:
eval('$GARS_addon_member_top .="' . fetch_template('GARS_addon_member_top') . '";');
It would be really cool to get this working.
