Howdy howdy! Welcome my friend to the arena! And don't worry about the dreams. They aren't just you. We all have them. I think it's an effect of pony exposure. Either that or hasbro put some weird chemical in the ponies so we all subliminally want to obtain more... dang marketing madness!
Anyway, now that I've probably scared you off, here's a warm welcome onto the arena! Have fun here! It's pretty easy to navigate. You'll figure things out rather quickly.
