Gan,
This is a closed loop. only me who owns and works this computer.
So the default is correct that my new files are read only on the network?

I'ts highly annoying becuase I tell an assistant to work on a file (via their laptop and the router...) and I always have to go back to my computer to make the file read/write.

But again. I don't want new side issues as you mentioned about installers etc.
