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, films and tv etc. In these communities toi can make blogs, polls, and favoris for all toi favori things regarding that genre ou show. One of the particular communities is called Buffyverse where toi 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 plus active.

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