Slack users tend to be passionate about the popular collaboration tool. “Slack has changed the way we communicate internally,” says Rob Shapiro, senior director of product strategy for Muck Rack, a digital PR and journalism platform. Slack’s easier access to shared files, discussion areas and notifications “made our team smarter, faster and more in tune with one another,” he adds.

That passion also tends to lead users to find ways to get even more from the app, which can be downloaded for Windows, for Mac and Linux.

We asked people from the Slack user community (as well as the company itself) for their top tips, tricks and hacks. These are 20 of their favorites.
