As a team working on a project, the desire to develop a community around an idea must have occurred more than once. It allows you to centralize knowledge about your project, your audience, their problems and how to solve them.
We needed to build a community to exchange with them, allow them to learn and help each other.
There are, for example, applications that allow for gamifying the community, retrieving statistics and program bots, such as launching quizzes.
Based on out experience, we are convinced that Discord has allowed us to grow our community faster than Slack would have.
