PSA: #Resilio Sync for individuals is on sale right now. I've been using it for years to keep my important files distributed to all my computers, without a Dropbox-esque server that's under someone else's control.
It's also great for managing my #plex server. I just add files to the #sync directory on whatever computer I happen to be at, then when the file is synced to my media server I can delete it off my local machine.
A tiny, intentional community of writers and people who really like frogs.
