My Spaces
Add your favorite spaces, or ones you'll visit regularly, to your list of 'My Spaces'. They appear on the Confluence dashboard, so you've got quick access to them. You can also use the Spaces List Macro to display them on a page.
To add a space to your list of 'My Spaces', navigate to it and hit the star icon next to the Space Name.
Save for later
If it's a page or blog post you need quick access to, rather than a whole space, hit Save for later and it'll be in My Work on your dashboard. You can even use the Favorite Pages Macro to display a list of all of everything you've saved for later.
@mentions
Use @mentions whenever you want someone's input. Mention a teammate, and they'll get a notification with a link to the page, post, or comment. Mention someone when creating a task , and the task is assigned to them. Find all your assigned tasks in your profile.
Mentions are a great alternative to email. If you want someone to look something over, add additional information, or approve anything, assign it to them as a task. They can make any changes or comment in Confluence. They may even let you know they're done by mentioning you back 
Watch a page, blog or space
Keep track of changes made to a page, post, or space by watching it.
Watching something means you'll get an email notification when there's an edit, a comment, or a new attachment.
When you watch a space, you're also notified when pages are created or deleted in the space.
-
To watch a page, go to the page and choose Watch > Watch page. To watch the whole space, choose Watch all content in this space.
-
To watch a blog, navigate to that blog and choose Watch this blog.
You can manage watchers for any space you're an admin of. It's useful when you're creating a new project and want team members to track its progress.
Go to any page in the space and choose Watch > Manage Watchers, then add or delete any names under 'Watching this space'.
