I've set up its own community: !ballisticng@sopuli.xyz
The plan is make the occasional relevant post, but long-term I'm thinking of hosting online sessions, and perhaps eventually even run some tournaments if we can get the racers together for that.
As AG racing can have a giant big skill-gap, I would also be nice facilitate the tutoring of new players, and if there are enough of us, divide players into different "leagues" by skill level.
It might be fun to track race results over a longer time as well, and have a sort of lemmy-leaderboard :D
If participating in any of that sounds appealing, come join us!
