You could pick it up, easiest server O/S there is.
lots of networks stuffs.. and different machines and licenses and all that..(I don't understand what all that means... LOL!) I used it can surf with it and can use it like windows XP.. LOL but I don't know how to network and all that stuff... I never tried it...
While it's definitely a decent server and fairly easy to configure, I think the "easiest" crown has to go to OS X Server.
