Hi- my wife and i share a computer, but use seperate accounts for seperate mail accounts, etc. here is a problem that bothers me from time to time: when one of us creates a new file/folder, by default it is read-only to the other user. we are both administrators on the machine, but still we run into permissions issues. for myself, i can override the settings for a particular file/folder by changing the permissions, but my wife is not so technical. we trust eachother and prefer to have complete access to eachother's files, since we share many. is there a way to set default permissions for new files/folders to be more open, easier to share with multiple users? also a related question i've had is, is it possible to share a common iphoto/itunes library between two different user accounts? for example, when one person uploads a new itunes album or new photos, for the other person's library to be automatically updated as well? thanks.
