I have a small server that I've been using for stuff internal to our house - running Plex for the TV, mostly. I'd like to make some of the documents on it available for my friends to download over the internet, but I'm wary of installing something like Apache and running a full-on web server if I don't need to.
Would it be a better idea to try to set up an FTP server instead? Or another option? Is there a 'correct' way to do this?
(For the purpose of this question, my friends are capable of following technical instruction to the level of being able to connect to an FTP server, but not much further. They are running a mix of OSes and are in various locations around the country.)
