You can see this in the following screenshot: Add a regular network user [ 40 ] Chapter 3 After the Super Admin has added Bianca, Sydney can log in to her dashboard and send Bianca a request to join her site. Sydney would click on the Users navigation item on the left-hand menu and then click on the Add Existing button at the top. I've highlighted that button in the following screenshot: Add existing User Button location Now you should be on a page titled Add Existing User.

However, Sydney would not be able to create a site specifically for Bianca on the network. That permission is reserved only for Super Administrators. In many cases it's useful to have multiple Super Administrators. For example, I could add Kayla as a Super Admin so she could add sites to the network without the need for me to do so. This is especially useful if I'm incapacitated for whatever reason. To add another Super Admin, go to your Network dashboard (/wp-admin/network/) and click on the Users navigation item in the left-side menu.
