I recently started a forum called JSerraforums.com. The name of our school is JSerra Catholic High School. They contacted me today, and had issues with it using their name, and if we do use their name, we would have to implement their own rules and make some members of the faculty moderators. I've checked the trademark site and have seen no trademark for JSerra. The name JSerra is based of the saint Junipero Serra. The road our school resides on is also named this. 3 Blocks down there is a school called "JSerra Continuation School". I was just curious if anyone could find a trademark on this name, and if we can continue using it. Also, say we cannot if I change the name to say "JS Forums" and remove all instances of "JSerra" off the site, can they regulate or take legal action against this?

Thank you very much.
