I appreciate your interest on posting in our website. But you have mentioned you will articles related to socio-political and cultural aspects.My suggestion is to write articles related to Google plus.For that you need a Google+ account.If you don't have one,kindly request an invitation here, so that you can have clear idea on what is happening in Google+.
I don`t have Google+ account. Therefore request has been done by me to send me an invitation. Perhaps I shall not be deprived.
