Hi, I'm interested in the any% run, but am wondering if there's a Discord server for the community, or any way to discuss the run with other runners, as some of the skips are really odd to watch without having knowledge of the tech behind it

There is no server (to my knowledge) as the community is quite small. There's an old video guide in the Guides tab that might help, and also ThaRixers GDQ run which has some more explanation. Otherwise I feel like asking in this forum is the best bet, and maybe ping some runners on Twitter or such?
