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, 电影院 and tv etc. In these communities 你 can make blogs, polls, and 收藏夹 for all 你 最喜爱的 things regarding that genre 或者 show. One of the particular communities is called Buffyverse where 你 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 更多 active.

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