The Core Creator Forums are full of tutorials, questions other Core Creators have asked, opportunities to promote your work, and a place to put suggestions for future Core development.
The Frequently Asked Questions post on the Core Help Center is an excellent starting point to solve problems and get back to creation.
The Core Creator Discord is a live social space where there are frequently other creators available to discuss challenges and potential solutions. It also includes channels in other languages and a live voice chat. It's an excellent place to find playtesters and get feedback on your game.
