I found this site and I thought others may find it useful:

A joint project of the Electronic Frontier Foundation and Harvard, Stanford, Berkeley, University of San Francisco, University of Maine, George Washington School of Law, and Santa Clara University School of Law clinics.

Do you know your online rights? Have you received a letter asking you to remove information from a Web site or to stop engaging in an activity? Are you concerned about liability for information that someone else posted to your online forum? If so, this site is for you.

Chilling Effects aims to help you understand the protections that the First Amendment and intellectual property laws give to your online activities. We are excited about the new opportunities the Internet offers individuals to express their views, parody politicians, celebrate their favorite movie stars, or criticize businesses. But we've noticed that not everyone feels the same way. Anecdotal evidence suggests that some individuals and corporations are using intellectual property and other laws to silence other online users. Chilling Effects encourages respect for intellectual property law, while frowning on its misuse to "chill" legitimate activity.

The website offers background material and explanations of the law for people whose websites deal with topics such as Fan Fiction, Copyright, Domain Names and Trademarks, Anonymous Speech, and Defamation.

In addition, we want your help. We are gathering a searchable database of Cease and Desist notices sent to Internet users like you. We invite you to input Cease and Desist letters that you've received into our database, to document the chill. We will respond by linking the legalese in the letters to FAQs that explain the allegations in plain English.

Periodically, we issue "weather reports" assessing the climate for Internet activity based on the letters we receive and news reports. What areas (topics, legal categories, jurisdictions) are coolest to online conduct? What activities risk being frozen out altogether? What conduct gets the warmest reception?

I know about it because my buddy sent in a letter he got from Kellogg to them ( which can be viewed here: http://www.chillingeffects.org/acpa/...?NoticeID=4377 )
