Greetings! It is always a gesture of grace to contribute knowledge to a community of those who can most use it. I wish to just comment about the text itself. Please do not take this as offensive, or in any negative way. I have always been a mentor and a part of solutions, not the problem. So if you will...
May I suggest that if the original text was in a language other than English, that the person who is responsible for translation, pay closer attention to the results. Otherwise, may I suggest that the author be more diligent about proofreading the material.
I feel very strongly that the author is a very talented and knowledgeable individual; and even more praise is due for his efforts to help others in their endeavors. However, I also strongly believe that the audience is soon daunted by trying to translate the article, (at least grammatically), and therefore would quickly lose interest in completing the reading of the article. It is noble and kind to help, but it is tragic to consider that these efforts go to waste because they’re simply too difficult to read with any degree of continuity.
