I stumbled on eWritingPal.com through an educational resource that claimed they used it. Reading the text on their website is like reading a phishing email from Prince Rupert who wants to deposit $10 million into my bank account temporarily and let me keep 10% of it. Yeah, right.
I don't know how I could trust a proofreading and writing help service that can't form a correct, and much less - a beautiful and effective - sentence in plain english.
Many of the reviews on this site also smell of the same bogus writing, which really makes me wonder...
