I am very new to the whole FaceBook movement, but it is a wonderful and free marketing tool, as well as a social form of communication. Will I realize that there are different levels of privacy, I would like to know if it is possible for one to log onto their FaceBook page without anyone knowing you're on FaceBook. What a terrible inconvenience to be upgrading your content and your friends "pop up" wanting to chat (because they can see you're online). If it is possible, please give step by step instructions. Thanks. One more question. Sometimes I search for old friends to see what they are up to. I have no desire to be their friend, I'm just being noisy. Some times you are able to see their content and other times you're not, depending on their privacy settings. None the less, can the person I'm looking into know I was there?
