您好SallyAnnKS.

Hi SallyAnnKS.

SharePoint 2010网站的默认主页不包含网站用户" Web部件:您是否在使用自定义网站模板?
如果您具有足够的权限，则可以安全地编辑网站的页面并删除Web部件.

The default home page of a SharePoint 2010 site does not contain the Site Users web part: are you using a custom site template?
You can safely edit the site's page and remove the web part, provided that you have enough permissions.

再见.
