I've looked around a little figured out how to switch without having to type the password (by having a blank password). But then people say its dangerous because anyone can install software or see your files or whatever. SO MY QUESTION IS: Would this make my computer vulnerable over the internet with people being able to hack into it or whatever they do? Or is it just a local thing. People will be able to sit at my actual computer and see my stuff. I'm asking because its just me and my wife that use the computer so I'm not worried about her seeing anything, I just want to make sure I'm not leaving my computer open to anyone on the internet. Phew that was long. Thanks for the help.
