I don't know if anyone has done this yet so i'm gonna give it a shot.
There is an app called Amino for ios and android. Amino has a ton of communities for various interests like technology, anime, video games, फिल्में and tv etc. In these communities आप can make blogs, polls, and प्रिय for all आप प्रिय things regarding that genre या show. One of the particular communities is called Buffyverse where आप can discuss all things Buffy and Angel. I know that's what everyone already does here but this sis a mobile community that's a bit और active.
So I just wanted to put this out there in case anyone was interested. Just download Amino and look for Buffyverse.
