What is this laundry list of things the C&D says will happen if I don obey?
Your opponent may describe a parade of horribles to demonstrate with exquisite detail what it will do to you unless you capitulate. This list generally includes, but is not limited to: (1) ceasing use of the allegedly infringing mark or surrendering the domain name; (2) rendering an accounting; (3) posting corrective advertising; (4) obtaining an injunction; (5) recovering costs and fees. Though these things sound awful, they are not medieval tortures (although that may be a function of the fact that Torquemada never thought of them). Ceasing use of the mark is self-explanatory: your opponent wants you to stop using the mark. Your opponent might also ask you to surrender your domain name if they believe the domain name causes (or is likely to cause) confusion with their trademark. For example, under ICANN rules (the UDRP), you may have to surrender your domain name if the following three conditions are satisfied: (1) your domain name is identical or confusingly similar to your opponent
