What is Slack?
Slack is an online chat tool for teams. It replaces email in many ways, you can text, share files, add images, and you can have private rooms or public rooms for specific topics. The system stores all your conversations in one place that is searchable so a team member can easily catch up on the conversation. You can also have Slack alert you when your name or a keyword of interest is mentioned. It’s pretty cool and free for a limited version. Once you join one, you will likely join more.
Its a great place to get help with a tricky problem.
