Okay. I've installed Ubuntu on an old laptop, which I plan to stick in a drawer and never open again, for use as a file and media server, and all is going well except that I'm having some problems with permissions.

I set the Downloads folder so that it's shared through Samba and everyone and their sister has read/write permissions, which is how I want it. However, when a new folder is created inside of it, it does not inherit those permissions. Which is not how I want it.

Some googling has led to what appear to be solutions, except that they're all written for someone who actually knows what they are doing, which is not me. I've got the basics of Ubuntu down, but just barely.

Any chance someone can walk me, step by step, to a permanent solution for this? You'd have my eternal thanks.
