If you do set up a family Web site there are some privacy issues to consider. First, when you register a site you're asked to provide contact information including an address and phone number. Unless you want your home address and phone number listed, consider using an office address, a post office box or some other address and phone number. And, if you do create a Web site, think about what you post. I would avoid posting a home address on the site and would be cautious about what information you post about your kids.
Some parents are uncomfortable putting up photos or information about their children.
Others feel OK about posting a child's first name and photo. Some ISPs will allow you to create files or directories that are password-protected. If you visit my family Web site, pictures of adults and deceased relatives are on the main page but to view the kids' pictures you need a password that's available only to friends and relatives.
