Hey! guys, I have a travel niche site (online magazine) With very good following on social media But the problem is I am not good at writing stuff. I want to make it something like Tripoto.com where users can come and share the details about their journey. (user generated content) My Problems are 1) it's a WordPress site, What plugins I need in order to make people sign in via facebook? 2) how to approach people to make them write for you with spending any penny? 3) how can I monetize it?
