在此感谢玮少

我知道下面有了，可是我觉得这个比较完整，转贴自AL8 Forum。

首页四格(含高亮显示)修改只需3步,for Discuz! 5.0

适用版本:discuz5.0
作者:ytc
修改:玮少
修改文件:index.php
修改模板:index.htm
功能:含高亮显示,但会增加两个查询
演示:http://www.superairh...dex.php

1.上传模版indexfour.htm到templates/default

2.修改index.php
找

$newthreads = round(($timestamp - $lastvisit + 600) / 1000) * 1000;

在下面加上
