Here's a scary bit: According to the Domain Name Rights Coalition, the recently passed Anti-Cybersquatting Act says that if you register a domain name, and some company has a trademark on that name, they can demand that you turn over the name. If you ask for money, even a refund of your registration fee, they can sue you for $100,000 or more. So if you own a .com domain name, someone can file a trademark and take it away from you. You could file your own trademark, but then you get into the obscure world of trademark law, where things like use it (in a business sense) or lose it apply. The bottom line is that corporations now have first dibs on domain names, and if they take a liking to yours, too bad.
