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, sinema and tv etc. In these communities wewe can make blogs, polls, and vipendwa for all wewe inayopendelewa things regarding that genre au show. One of the particular communities is called Buffyverse where wewe 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 zaidi active.
So I just wanted to put this out there in case anyone was interested. Just download Amino and look for Buffyverse.
