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, Film and tv etc. In these communities te can make blogs, polls, and preferiti for all te preferito things regarding that genre o show. One of the particular communities is called Buffyverse where te 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 più active.

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