对于默认wordpress的用户权限只有：
Administrator管理员
Editor编辑
Author文章作者
Contributor投稿人
Subscriber订阅者
这五类，可是对于一些cms性质的wordpress，这给管理相当大的不便，有时候我们想精确地控制某几个人的权限，只可以修改自己的文章，且可以直接发表文章，而另几个人只能投递后通过审核才能发表，这个时候我们就可以安装一个权限管理的插件。它可以像操作系统中那样，建立不同的用户组，并给用户组赋予不同组的权限。
插件名称：Role Manager
插件页面：http://www.im-web-gefunden.de/wordpress-plugins/role-manager/
官方下载：http://www.im-web-gefunden.de/wp-content/downloads/plugins/role-manager.zip
安装说明：
下载插件后，解压上传到服务器的插件目录，启用插件，插件会在用户导航菜单下增加这几个管理项
Roles
Capabilities
Role-/Capability Management General
Role-/Capability Management Help
设置说明：请到后台的用户菜单下的roles标签下设置不同权限组的权限Roles，支持ajax方式的修改，不用重新加载后台，即可生效。
可以单独设置的权限包括：
