I have a few friends/family who backup important documents and the occasional system image to one of my hard disks via Tonido. Anyone know if there is a way, from within Tonido, to set a quota on a particular guest user's assigned share? Can't find anything about this via search, and I'm thinking you have to upgrade to the paid FileCloud for this feature. If that's the case, I was thinking of whipping up a quick directory watching app in C# that would run in the background and email friends and family when they're approaching their quota. It would, of course, email me as well.
