I joined Facebook a long time ago, but couldn't figure it out because it was so different from any other networking site I'd been used to, so I didn't use it for at least a year, long enough to forget I'd created the profile. So, there are two of me on FB. One I can't access myself, so I can't respond to anyone who ever tried to contact me there. The only real reason I use it anymore is because FB's the only way I can stay in touch with certain people.
