回复：怎样注册域名？

Have look here: http://en.wikipedia.org/wiki/.org

"Anyone can register a .org domain; there are no requirements for registration. .org was recommended for and perceived by common public to be of non-commercial entities, however there are no such registry restrictions similar to those with .gov or .edu top level domains. There are many instances of .org being used by commercial sites, although some people question whether it is ethical to do so. .org was also commonly recommended for use by individuals, although .name and .info are now alternatives.
