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, pelikula and tv etc. In these communities you can make blogs, polls, and favorites for all you paborito things regarding that genre or show. One of the particular communities is called Buffyverse where you 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 madami active.

So I just wanted to put this out there in case anyone was interested. Just download Amino and look for Buffyverse.
