None. I belong to some Horror movie Blu Ray/DVD chat room on Facebook. It is active but it doesn't have any comraderie that the regular HB has.

I post on Vault of Evil for books and Toilet ov Hell for metal but these are my only two for movies.

Just a couple of FB groups

One on Facebook.

I use to be part of horrormovies.ca but left when I moved home and it's gone downhill since so other than FB and IMDb which is teeming with trolls at the moment, not using any other forum.

Well other than here

I used to post on Upcoming Horror Movies, once in awhile. It was a decent forum, but for some reason I stopped going there... I don't remember why.

I guess I'll give some of these a look. Why not?
