Hi, it looks great but I cannot seem to get to grips with anything on my MacBook. When I try to connect to a wireless network, several present themselves, but they all require passwords, which I have no idea how I am supposed to know. Do you have to sign up to a network? I thought that the whole idea with wireless is that you can connect to any network in range of your computer, but as is obvious, I know virtually nothing about this stuff. I would be very grateful if someone could enlighten me...Also, does Apple have its own version of microsoft word, if so where is it?!
