Hey Sujit thanks a lot. But what do you think about Berryman blog post ? Is it feasible to apply or should i apply the synonym stuff ? which one is good? And the 3rd approach you told me about, seems like difficult and time consuming for students like me as i will have to submit this in next 15 Days. Please suggest me something.
