By US Law, my name is a trademark, (also known as a common law trademark), Because i have been doing commerce using it. I am in the process of having it be a registered trademark. How will you handle the trademark violation of someone using my name. It is rumored that DMCA takedown would invalidate it. This adds another overhead to my day as i have to search for my trademarked name everyday to see if someone is using it. This is required so my trademark doesn't get diluted. It sure would be nice if there were a place in Second Lief that i could register that my name is a trademark, espesially after i have it as a registered trademark. I know that Linden Labs doesn't want its trademarks diluted, why not extend the business people that use Second Life as a platform the same curiously. You wil definiately need to provide a mechanism to report the trademark infringement. And have a process in place to change the persons display name back to their username.
