The <a href="https://slack.com/" target="_blank">Slack</a> group messaging system can be overwhelming, but with Glenn Fleishman's real-world advice, new users can come up to speed quickly, and more experienced users will find numerous techniques for participating more efficiently. Slack is all about communication, so you'll learn how to write, edit, and react to messages; use snippets, posts, and audio calls to collaborate with team members; and create and manage both channels and direct message conversations. You'll also see how to configure Slack's flexible notification system so you're alerted appropriately but not nagged. Plus, Glenn covers how to search old messages effectively, how to make Slack your control center by centralizing reports from other services via integrations, and numerous techniques for improving your productivity in (and with) Slack.
