I would most definetaly meet the mane six, and possibly tell Fluttershy first that I know quite a lot of them, as I was following their journeys through a thing called a "computer screen", after which, I would explain everything to her. (I would only tell Fluttershy first, because I am scared that if I told either Dash, Twilight, Rarity, Applejack or even Pinkie, they would overreact... though not sure about it.)
Then I would very kindly ask Twilight if I can sleep in their castle for the night, and the next day, if I would be a pegasus, which I possibly would, based on my soul, I would ask Rainbow Dash to give me an in-depth tour of Ponyville!
