Dietician is spelled incorrectly. There is no second t in dietician.

In the title of the Ask the Dietitian site, DIETITIAN IS SPELLED INCORRECTLY!!! There is no second T in dietician!!
FYI, outside the US, many people spell dietitian as dietician (a -tic- in the middle) and in the United States, dietitian is spelled dietitian (a -tit- in the middle). Since the internet is worldwide, either spelling would be correct.
