I mean, I’m still using it, slowly filling the db… But yeah the first go (or 5) was super frustrating, and the UI could be more intuitive, almost wizard-like for beginners would make a huge difference. But if you want to note the warnings and proceed, it seems like a feature-rich system. Definitely aimed at the actual IT career individuals (and their businesses).
That is the container I’m using, also.
I have briefly looked at homebox, but haven’t put it on my server. From the description though, and the couple of pictures, is very likely a better fit.
