Chilling Effects has posted the Cease and Desist letter that I received from sms.ac. I know a number of other bloggers have received this letter. Take a look at their analysis if you've received this letter. Chiling effects has done a great job explaining it. Since I received the letter, some email has been exchanged with the lawyer and I extended on olive branch on a forum to a sms.ac employee, but I'm still not sure exactly where their threats stand at this point.
