I am complete novice in this. So I had to struggle with it a bit. Because I was getting some runtime error (wonder what is that !!)
So I will just detail some steps that I took for benefit of my fellow novices.
Go to Chrome--Settings--Extension (link on left)--Get More Extensions (which is at the bottom)
Search for Tampermonkey and download and save it.
Then when I clicked on the userscript link given by Harsha, i still got an error. I guess, it may work for some at this stage. If it doesnt then read on.
Then I saw Hari's tip. First open Harsha's file in notepad, select and copy the data (text). Go to the small button on the top right of the chrome browser which is the tamper monkey button. Go to Dashboard and click on add user script. Delete what may already be there and paste Harsha's data. Click Save.
Then it worked for me (phew!!).
But, great job Harsha !!
