KingCMS PHP版本的评论模块标签应该怎样写？

KingCMS PHP企业版（SP2）的文章内容模板里评论模块标签应该怎样写？如果想限制注册用户才能评论的话，如何设置？后台好像没这个功能哦。各位大侠帮帮忙！

每个栏目（单页面除外）新建的时候都有选择开放的用户组，默认是注册用户才能评论。

                    <!--本文的最近评论-->                   
                    <div id="page_cmt" class="fl m20">
                     <strong>本文最近评论<cite>({king:comment/})</cite><a href="{king:commentlink/}" title="了解更多">查看全部评论</a></strong>
                        <div id="page_cmt_result">
                         {king:portal.comment modelid="(king:modelid/)" listid="(king:listid/)" kid="(king:kid/)" orderby="cid desc" number="5" userhead='true'}
                         <div class="cmt_result">
                             <div class="cmt_avatar"><p>{king:avatar/}</p>
                                 <ul>
                                 <li><cite><?php if('{king:username/}'!=''){echo('{king:username/}');}else{echo('网友');}?></cite>说:</li>
                                    <li>{king:DATE formatdate="Y-m-d H:i:s"/}</li>
                                    </ul>
                                </div>
                                <div class="cmt_conn">{king:content/}</div>
                            </div>
                            {/king:portal.comment}
                           
                        </div>
                    </div>
                    <!--评论表单(#userhead是必需的用来更新头像)-->
     <div id="page_cmt_form" class="fl m20 br">
                        <strong>请谈谈你对"<cite>{king:title/}</cite>"的看法</strong>
                     <div id="avatar" class="fl w720">
                            {king:user.state id="usercmt"}
                            <dl><dt><span id="userhead"><img src="/images/headface/default.gif" /></span></dt>
                             <dd><a href="#" class="k_user_login">登陆</a></dd>
                            </dl>
                            {?king:user.state}
          <dl><dt><span id="userhead">{king:avatar/}</span></dt>
        <dd><input type='hidden' id='username' name='username' value="{king:username/}" />{king:username/}</dd>
          </dl>                           
                            {/king:user.state}
       <label><textarea id='kcontent' cols="60" rows="5" name='kcontent'></textarea></label>
                        </div>
                        <p><a href="javascript:;" class="k_ajax" rel="{URL:'{config:system.inst/}portal/index.php',CMD:'comment',modelid:{king:modelid/},listid:{king:listid/},kid:{king:kid/},username:$('#username').val(),kcontent:$('#kcontent').val()}">发表评论</a></p>
                    </div>

非常感谢，我回头试试看，能不能行。呵呵。

默认用户组好像不起作用哦，新建了一个栏目设置为默认用户组，文章评论的时候照样可以不注册就能评论了，还有不知道后台如何审核啊？

来看评论的，，嘿嘿
