Linux goes to school with NethServer

Nethserver for school isn't a bad idea: your description says, it's for small organisations so it could fit. I could try to promote it in our school but there is a big problem: The school's website and our files are situtated in the educational part of the governement's servers ans in MS Office 365...(If you want to do a research -->myschool.lu Warning, it's written in french.) But I could ask if we could take Nethserver as a VPN-Backup server= Copy of the files in a VPN, like universities.
Nethserver is recommended in our school, because our "IT-specialists" (They don't even know how to secure a router) aren't familiar with Linux so they could learn using it in a more easy way.
