These are reproducible questions that help the world.

Generally, these are not very opinionated questions. + +These are questions like "How to convert bytes32 to uint256". + +## Generic Theoretical Questions + +These are questions that likely do not have a canonical answer. These are questions like "which blockchain should I deploy to?" or "How could I make a game that involves many random characters?". They belong in places like: + +- The "General" discussions section of this course +- A generic forum like Reddit, Twitter +- Discord (like some of the ones people have started here) + +Ideally, you put these on an indexed forum like reddit and the general discussions section instead of discord so others can do a web search for the problems. + +## "In the know", support, or emergency questions + +These are very specific use cases and 99% of your questions will not be these kinds. These are questions like "we just got hacked, can you help us?", "Want to join my team", etc. They are questions that likely only apply to your situation and what you are doing.
