I just noticed that in the "Arthur_(series)" tags, various members of Arthur's family have their last name spelled differently in the tags. Arthur, father David, and baby sister Kate are tagged with the last name "Read" (the correct spelling), while mom Jane and little sister D.W. are incorrectly tagged with "Reed".
My knowledge of this show is somewhat limited, so I have no idea if there may be other extended family members whose tags also need correcting.
