In my view the best thing would be for this question to be closed without grading. If there is anything more to say about the term "chief fellow" it would be better to say it in the recent question from the same asker on the same term, which is still open:
http://www.proz.com/kudoz/5983154As you will remember, only a couple of weeks ago I answered a question on "fellowship", for which there was already a correct answer in the glossary (by María Claudia). I felt at the time that I shouldn't really have done so, and only did so because the question was open and incorrect answers were being posted. Personally I don't want to do the same thing again here.
