Nice! I applaud you on opening a forum with all these FaceBook groups infesting the internet. It is quite hard to get membership when most people like the ease of posting on FB.
I, myself opened a forum two years ago but I opened it with 6 other people from around the world that I met on horror message boards. It's still going great but caters to the indie/underground scene.
Your site looks great in my opinion, one of the best new ones. I'll join. I already post on three forums daily including my own. I also mod two of them upcominghorrormovies.com and BloodyDisgusting. Its really fun and I wish you all the luck in the world.
Its funny...I did a similar advertising when I introduced my site...with music..
Here;
kinda lame..
I used this song...oh gosh.
