Hi, Hardik, thank you for your interest in writing for HHH. I presume you've read the guidelines, as this is where we're having this conversations. One of the guidelines states clearly that you must be a member of Medium, but you aren't.
Due to the restrictions and limitations in your ability to properly participate on Medium as a non-member, this means you would also be limited in your ability to engage fully with our HHH community, and it IS a community - a "Pub Family." At the very least, it would be unfair to the others who are members.
Thanks for your interest. Best wishes to you.
