Welcome welcome welcome! :) I don't watch Supernatural but my best friend is obsessed. I wish she were on this forum, I'd totally tell her to talk to you. XD;
But yeah, like Krieg said, we have a very active MLP club in our Clubs & Groups board that was calling your name. I see you've already dropped off a post so we all certainly hope you'll enjoy participating. I used to be obsessed with the series in 2011; it's ridiculously adorable. I can only hope to draw that nicely one day!
Be sure to stick around and have a lovely time here. I'm always around if you need someone to talk to or are confused about the forum. Never hesitate to contact a staff member. Cheers, Shiarra! <3
