As a professional educator and writer my principal editing roles are fixing grammar, punctuation and style problems in articles. I believe that articles should be written in a straightforward and modern English style (not in a convoluted and outdated 19th-century style as so many articles sadly are). I have a low tolerance for the many editors who frequently misuse articles for promoting their personal opinions or their uncritical or ideological following of belief systems, as well as any kinds of hype, advertising, slander and blatant bias. I do not make too many editing mistakes and I am always happy to have any mistakes corrected if done politely and with reference to the Manual of Style instead of merely personal preference.
