Frustratingly and for reasons unknown, Yahoo Answers has a very limited 4-day period during which one can post answers (boo, wasted some time trying to figure out how to be helpful). In response to "When was the first E-journal published on Yahoo Answers India", , my answer is:
According to the Bryn Mawr Classical Review, it is the second-oldest e-journal every pubished - http://bmcr.brynmawr.edu/about.html in 1990, and it reports that it was beaten to the punch the same year by Postmodern Culture - http://bmcr.brynmawr.edu/footnote.html
