How to get in touch with the community
The topics listed previously and many more are subjects of daily discussion by the community, a place for understanding use cases, arguing about different implementation approaches, and organizing efforts to cooperate. Anyone is welcome to join.
The primary channel is the forum at https://forum.crystal-lang.org/. Any kind of discussion can happen there, from hypothetical features to seeking help and code reviews, from looking for Crystal jobs to sharing projects you've created.
If you are looking for other ways to interact, please take a look at https://crystal-lang.org/community; it aggregates links from many different platforms.
Finally, there is the GitHub repository, where collaboration about the language's development happens, at https://github.com/crystal-lang/crystal. It is the place to go if you want to contribute to the standard library or the compiler itself with code, documentation improvements, or issues.
