I have known since you arrived that you were a different person, never thought you were the doc, but I can see there is a need for clarification : ) well done.
you can email the ed from the my profile option top left, explain your reasons and they can change your registered name i believe. It is a shame though, as doc spock has several ids I think, and it wouls be a gesture from him to agree to use his other name(s) and delete the doc.
