Well, I do not want to care what Pheelyks and his psycho fans believe in. It seems they forgot the fact that some of the so called 'English-based writing companies' employ ESL-Writers. Besides, all the legit writing companies do not just wake up one morning and start picking writers randomly across the world, do they? They take the applicants through some serious screening test. I want to believe English test is mandatory. By passing the basic English test,you would have proven you can write.
I would agree with my friend Researcher on this: It's not all about English, but you must also be knowledgeable and experienced enough in a given subject to produce high quality paper. You must also be very knowledgeable regarding the academic writing styles and formats. Without any experience in the APA,MLA, ASA, Harvard, Chicago, Oxford etc. your perfect English will not count much in an academic writing industry. You will agree with me that not every EFL writer can solve all the problems in calculus or Physics. Think, Pheelys, think! To be honest, I am so disappointed in you.
