A website can be a site or a collection of sites. If it is a collection of sites, the site has a top district site and then school subsites below it.

From Site Manager select SITE & CHANNELS. Select the name of the site to open the workspace. 

If you don't see SITE & CHANNELS, contact your district/school webmaster to assign you permissions as a site director.

To access a different site or subsite workspace, move your pointer over Change Site. Select the name of the site or subsite you want to access. 

This is only available to site directors and only if your district subscription includes more than one site.
