My Favourite Mane 6 Pony: Twilight Sparkle How did you find MLP Forums?: By the MAAAGICAL powers of the internet.
How you became a fan of My Little Pony: Friendship is Magic: I was at my cousin's house and they turned on the TV, accidentally to MLP. They don't like it, but I was hooked. It was the pet episode with Rainbow Dash, the scene where she's whistling in the canyon during the race.
Been a fan since season 2, huge lover of fan creations, etc., etc.
