Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
Super happy to hear that! We've put a lot of work into it, make sure to come hang out with us on the discord if you haven't already joined! Would love to have you there https://discord.gg/v2DzTQPjhp
It's kind of a long story but you have to do it naturally. We were playing around with the idea, decided it was fun, and approached the National Dex leadership because that's what seemed to be the best fit for the tier regarding assistance running it and a place to host it.
I don't know if there's interest in the normal BH community, but people in the ND community and sometimes the Doubles community were asking for it and we were able to fill that void.
