If you’re operating a website or conducting internet-based business, what you don’t know may hurt you. Dangers abound: your contractors could infringe on others’ copyrights and trademarks; others could infringe on yours; you could be held liable for mistakes or omissions on your website; your legal contracts with your online customers could be deemed unenforceable; and your visitors’ behaviour on your site could land you with a libel or slander lawsuit.
