下载的jeecmsV6搭起来后，首页上的【论坛】链接到了www.bbs.jeecms.com官网论坛上来了，这部分是不是需要自己二次开发啊？ 想整个能发帖的功能比较全的网站。 有大神弄过的，赐教一下，没配好还是本来就没有开发这个模块。

论坛没有www

哦，我以为浏览器隐藏了，我的意思就是连接到官网论坛上去了，不像别的板块连接到localhost的某个链接下去。
亲爱的版主大人，这个模块系统不吗？

什么意思，不就是个外部链接吗？

系统搭建起来后，论坛这个板块需要重新开发吗？

对啊，我的意思是不能像留言板一样有自己的板块吗？

cms系统和论坛有什么关系，管理论坛我们有bbs系统

是我low了，我当时没有下载bbs系统。但是最近部属上以后跑起来了，前台正常，后台不知道什么原因报错了，请赐教！
