Do you know your online rights? How often are legal threats used to silence Internet activity? Help us to find out and counter baseless threats with the "chilling effects clearinghouse." We are gathering a database of cease and desist notices sent to Internet users, and analyzing those letters in issue-spotting FAQs (informal memos) to be posted on the site. The site also offers background material and explanations of the law for people whose online activities include topics such as fan fiction, copyright and the Digital Millennium Copyright Act, trademark and domain names, anonymous speech, and defamation.
