Am surprised to see this question from one of the top earner.
What deepti suggested is just the points and cash system of boddunan.
To earn more cash and points, you need to be
1.Active in forums (atleast 25 posts per day). this will make you to achieve good status on forums too.
2.Be active in voting polls and commenting on articles(This is the best way to earn minimum 50 rupees per day)
3.Participate in all contests!
Participation is more important - You can earn upto 65 points per week just by participating.
4. Write atleast 1 article per day - You can earn upto 100 rupees per week provided you are good in writing articles.
5.Submit documents - if you are good at surfing collect question papers and project reports and post it here. you can earn maximum through this.
if you do all these, you can automatically become forum supporter of the week with high points and also you can get more revenue sharing.
Hope my points are valid.
