Yes.
Notice the logo at the top of the page. it has the superscript TM notation. If it were a Registered trademark with the trademark office, it would have the circled R ® symbol. It's a common fallacy to think that just because a name isn't registered, that no TM exists otherwise. Namepros is a valid TM without being registered.
Also, look at the trademark on the uspto.gov site and see that it is for a different purpose for computer software, not a web forum. It was also used as far back as 1994, well before this forum was started, and is not an exact match.
