 For longer-form conversations about React, we've set up a [discussion forum at **discuss.reactjs.org**](https://discuss.reactjs.org/). This forum is a great place for discussion about best practices and application architecture as well as the future of React. If you have an answerable code-level question, please post it to Stack Overflow instead.
 
 In the forum there's also a category for job posts and a category for discussion of our weekly meeting notes.
