The Team Feed is the best way to keep an eye on the proceedings.
Send notifications to your crew.
Do away with having to call a meeting for every little thing!
Everything, in a nutshell.
The Notification Center brings you every recent development you need to know about in a non-intrusive way. Here, you can interact with your colleagues, and use tags or @mentions to alert them of the latest events.
Labels are good.
Just like bookmarking a page for future reference, you can tag help articles and even tickets for future use. These tags come in handy when you're working on an issue that's been dealt with before and need to quickly find resources.
