Hello Jeevan Kumar,
Thanks for your well wishes. There is no fixed procedure to become webmaster of a site, but what is necessary that, you should show your worth and pro activeness by posting self written articles on a regular basis in the resources section of the site as that is the section which brings most of the revenue.
I have seen you active in many sister sites and you are doing a great job everywhere, so keep doing the good job here also. I firmly believe that you can help us in taking this site to greater heights. We have to do it together, like Dhoni and boys did it for India.
If you have any suggestions, you can always contact me or share with everybody in forum section. Looking forward to active contribution from you and everybody.
