The latest GhostBSD is looking much better than even a few months ago. Earlier this year, I'd posted a comment about the need for a GUI user administration tool. This topic still needs addressing.
I'd used MATE user admin on a previous version of Ghost, but it's not supported in the system repository. In a previous thread, one developer replied to me that making this program work in XFCE was a major job.
User administration is a core system function and we must have some type of GUI for normies to use. After all, that's the point of having a GUI in the first place. While most of us can easily go to the command line, that's not an option for potential users who simply use computers for regular tasks.
While many systems have only 1 user, the need still arises when installing some applications and device modules that require different group permissions. I've added some serial devices for ham radio that I could not access until I added my user to the appropriate group. This also held when I added scanners to the system.
I may also wish to create accounts for my wife and children to use the same system.
In reviewing different packages on Linux that would do a good job, the Fedora user manager looks quite good. One thing I like about it is the easy access to the UID when creating a user - this is important when using NFS on a network as the UID/GID control access and not the user/group name. I've used this on my network with Linux and Macs.
I look forward to comments. Please, don't reply telling me I can use the command line. I will hate you if you do.
