I have really started hating WP for a minute, and started using Grav on a New build. Its great, fast, fun and easy to use...but super limited, so I'am going back to WP until a better option comes along.
If you have never used Grav get it. You can take the basic theme and tweak it to perfection. But once you start to get into added functionality, you will see how limited it is.
Grav is cool, you have some different options there, but it call for work with terminal
"You can easily add other users but it requires a bit of work in the terminal/command prompt to do. From your terminal, access the root of the Grav site you'd like to add users to, and type the following command:
bin/plugin login newuser
This will initiate a series of prompts to guide you through the creation of a new user. These include creating a user name, password, email address, and setting the new user's permissions level."
