Users / Groups / Shares Confusion

[JonnyAlpha]

Hi;

After much research and following several "different guides" I am still thoroughly confused with regards to setting up a user account / groups and shares.

What I want to be able to do is access my files (Music / Video / Documents) on my NAS from all of my devices (Macbook Pro OSX 10.5.8, iMac OSX 10.5.8, Windows XP Pro, Windows 7, Apple TV2 Jailbroken with XBMC, Android Phone ES File Explorer).

There will only ever be one person (Me) accessing the NAS, but through several different devices, so please, please, please can someone point me to a guide or explain how to set up a single user system (Without Password Access), that I can access using all of my devices.

I did manage to get it working yesterday from Windows XP and even started to view videos over my Apple TV2 but this morning when I switched everything on a again I cannot access it from any device (I have never managed to get AFP working.

UPDATE: Just created a new AF share following another guide I found on a web site "SteveStreza.com", once I completed it I actually managed to connect on my Mac as a guest in finder but no files or folders were visible?
