Adding admin user accounts I'm lost when it comes to adding a new admin user account. In the dashboard, I go to Settings -&gt; Users, where I'm expecting to find a form where I could input a username, email address, password, etc.  Instead, I'm presented with a blank field layout. So I'm supposed to manually create fields for the username, email address, and password? What fields do I need to add and how do I know what to name the fields? Is there any documentation on this?
Neither the users documentation page nor the user management page offer any help. However, on the User Management page I read this sentence:
  To enable public registration, go to Settings → Users → Settings, and check the &quot;Allow public registration?&quot;

When I go to Settings -&gt; Users -&gt; Settings, all I see is a field to change the User Photo Location and a Save button, nothing else. I'm not trying to enable public registration, but the fact that that option is missing makes me wonder what else is missing.
I don't even know where to begin. Can someone point me in the right direction? Your help is greatly appreciated.
Upon setup, Craft is installed with a free Solo license. This means that the user generated as part of installation is “the only account you will be able to create.” (From the official User Management documentation)
In order to create more users, you’ll have to upgrade your installation to the Pro version through the control panel’s Plugin Store. Pro is free to test and develop with.
