Frankly, Me too confused. The first reason was the author of the thread Ms. Juana, one of my favorites in ISC and known to be proficient in English. On verifying the link provided by Gypsy, first I wondered whether I have approved the question. But for sure, I never commit a mistake in choosing 'between' and 'among' as there was an exclusive examination for English Grammar (as paper II) in our SSC and my father used to bang me for such little errors in our practice examinations. Then who would be? We checked it and presently the Editor is not available and on tour, also who never commits a mistake. Again a doubt - if such a phrase exists! May be, if it were a simple typo error, our members would remind it to get it corrected via PM.
Finally, it is understood that it was a typo error and once it is approved without verifying the text then there is no provision to view the approved abstract of the AE question and the next AE question would be displayed on the screen for review. This is also an experience and we would request the WM to design such programme as it happens in other sections such as Jobs and articles. Now, necessary corrections are made in the said thread.
So, I got the essence of this new phrase "On among the tow"- Editors, you too take care of the typo errors , else the meaning may change.
No offences meant, making this comment sportively. I am locking this thread.
