Swati u always quote your source so I found it kinda disappointing when u didn't this time. Don't want to sound like a professor but this comes close to plagiarism. I wouldn't tell others had they done the same thing but I know u will take it in good spirit. I read this er.. article in an Indian site like a year ago. for all those who want to yell at me for ruining the mood of the thread, don't expect me to reply to your yellings right away. I "might" do it after a week.
