If you work with WordPress MU (WPMU) then you know that you have a few options when issuing user accounts to people. This video tutorial shows how to add users to individual blogs as admins versus adding them as a Site Admin which would grant access to all blogs on your WPMU install.
Please enable Javascript and Flash to view this Viddler video.A Site Admin has access and ability to do everything and anything on your WPMU install and you can set any user as a Site Admin that requires this access. But this should be few and far between. Most users only require access to one of in some instances multiple sites, not all.
To make users a Site Admin, go to the Options area under the Site Admin section in the left side bar when logged in. If you do not see this section then you are not a Site Admin and you will need to contact a Site Admin for that WPMU install.
To make users an admin for one or more individual blogs, simply go into the Backend of the desired blog(s) and go into the Users section. Here click the “Add New” link and you will be prompted to enter the person’s username and email address.
If the username you enter does not exist then WP will add that user. If it does exist then it will add that user to this blog with the role you specify. (Note that the email address associated with the username must match. If they don’t then WP will not add the user).
If the username you enter does not exist then WP will add the new user account, so long as the email address you enter does not exist either.
Setting this user to Administrator does not make him or her a Site Admin. It only makes him or her an admin for that particular blog.
The check box for sending confirmation email is not checked by default but I recommend you check it. If you do not then a confirmation email will be sent to this user requiring him or her to click a verification link before he/she can access the site. Checking this box simply adds the user with the role you specify.
So that’s it. It may seem confusing at first but once you go through it a couple times it makes more sense. The important thing to note is that you can make people admin users to individual blogs on the same WPMU install without having to grant them access to your entire WPMU site.
