I'm in these communities:

I do free coaching to help get beginners into fighting games over at the New Challenger discord server!
We're the largest beginner community in the world! Reach out!

I also help run the SF6 Resource Hub, a discord server meant to take away the clutter and disorganization of character discords and ease the pain of reaching across the aisle to learn specific matchups and find resources.
