Thansk for sharing Suhasini

Hi Suhasini,
It's nice to see more people from TeraData domain and I visited your website. 

Few questions for you:

  • Your blogspot doesn't seem regular and popular. Are you regular there (except this month)
  • Have you developed that for monetary benefit or for knowledge sharing?
  • Are you planning to post on regular basis with detailed explanation like screenshots, codes etc?
I would rather suggest/request you to be an active member here, instead of getting backlink from your and making redundant posts :(

Few benefits for you and others:
  • Your and posts will be much popular here then the blogspot space
  • you will find more people from your domain and will learn more with sharing motto.
  • You can learn other technology, language and tips from here
  • We are popular over internet and we are trying to make a non-profit common platform for poeple who wish to learn more technical things while sharing.
All the best Suhasini
