Hey, A fellow andalusian :) Guadalinex was my 2nd distro to try, computers at high school had it installed and we got install CDs to try it at home.
They also did courses at the Guadalinfo centers in rural towns, my grandpa actually learned to use a computer there so I installed Guadalinex in an desk PC and gave it to him.
At least at the Guadalinfo center in my hometown they still use Linux, I think it's Linux Mint, and they keep giving free IT Courses with it.
There's a new Andalusian distro focused for education, seems to be used in schools, but I don't know much about it
Thanks for creating the community! I just followed it, will try to participate soon
