Restricted access in all sections of the site

Sir I am member of India Study Channel. And also I had tried to register with all the sister sites of the ISC.
I want to post some articles on But I am having message of "restricted access" in each section of the site.
Does this site going to die or you are not having any time and hands to solve the issues on the site.
Please do the needful for this.
Thank you
