首先找到dede默认模板里的article_article.htm文件，找出其中的
<div class="comment">
            <!–评论:标题–>
            <div class="commenttitle">
                <div class="title"><strong>最新评论</strong>共有 {dede:field name=’postnum’/} 位网友发表了评论 </div>
                <div class="gotopost"><a href="{dede:field name=’phpurl’/}/feedback.php?arcID={dede:field name=ID/}">查看所有评论</a></div>
            </div>
            <!–评论内容–>
            <div class="commentbox">
                <script src="{dede:field name=’phpurl’/}/feedback_js.php?arcID={dede:field name=’ID’/}"></script>
            </div>
            <!–发表评论:标题–>
            <div class="posttitle"><strong>发表评论</strong></div>
            <!–发表评论–>
            <form action="{dede:field name=’phpurl’/}/feedback.php?action=send" method="post" name="feedback">
            <input type="hidden" name="arcID" value="{dede:field name="id"/}">
            <div class="postbox">
                <div class="txtbox">
                    <strong>评论内容：</strong>不能超过250字，需审核，请自觉遵守互联网相关政策法规。

                    <textarea name="msg" cols="60" rows="6"></textarea>
                </div>
                <div class="userbox">
                    <dl>
                        <dd>
                            <strong>用户名：</strong><input name="username" class="username" type="text" maxlength="20" />
                            <strong>密码：</strong><input name="pwd" class="password" type="password" maxlength="20" />
                        </dd>
                        <dd></dd>
                        <dd class="mtop"><input name="notuser" type="checkbox" value="1" /> <strong>匿名?</strong></dd>
                        <dd><input name="sb" type="button" class="submit" value="发表评论" onClick=’javascript:if(document.feedback.msg.value!="") document.feedback.submit(); else alert("评论内容不能为空！");’/>
                      </dd>
                        <dd class="mtop"><a href="{dede:field name=’memberurl’/}/index_do.php?fmdo=user&dopost=regnew" target="_blank">注册</a></dd>
                    </dl>
            </div>
            </div></form>
        </div>
    </div>
(这些就是评论那一块的所有代码)
2，找到以上代码中的
<strong>密码：</strong><input name="pwd" class="password" type="password" maxlength="20" />
然后删除。
找到
<strong>匿名?</strong>
然后删除。
找到
<input name="notuser" type="checkbox" value="1" />
,然后更改为<input name="notuser" type="hidden" value="1" />.最后提交保存，OK了，大功告成！
