New Brevoort Formspring

Just wanted to say that as a white male, I am really enjoying the diversity you are helping to bring to Marvel comics. How does one evolve if change is not a part of it. I do have a question, however, merely a matter of semantics. When the woman who picked up Mjolnir became Thor, did she strip the "Thor" name from Thor Odinson, or merely decide to continue using it to help establish herself as a new hero? I ask because other characters have picked up Mjolnir and did not use the Thor name.
