My wife and I have files we want to share that are in Dropbox and are synced to our computer in my local Dropbox folder. She has her own local account on the same machine and I want to know if I can locally share a folder from my synced Dropbox folder with her. Is it possible, and if so, are changes she makes going to be synced to Dropbox.com? I have looked at using Dropbox Family and the Family Room folder to do this, but if we both sync that folder it doubles the storage space used. Any thoughts or suggestions?
