First off, it’s great to see that long-standing question answered with some confidence.
Second, I’ve long dreamed of an English equivalent of the Japanese old-back wiki. Does anyone have experience running websites such as that? I’d love to help create a unified, comprehensive resource for retro rulings, translation fixes/clarifications, etc., but though I may have the knowledge and passion for Pokémon research, I don’t know anything about creating a website/wiki/whatever.
