Update: guide now available.
I am in the process of writing my file sharing guide for Leopard and Vista and though similar to Tiger and XP, there are some quite fundamental differences which means it is taking longer to write the guide then I first thought.
I have recommended using the same username and password on home networks for sharing files as it makes it easier to share files.
Now with Leopard you can share individual folders much more easily, which means I may write two separate guides rather than one long one.
We’ll see how it goes, expect it soon.
