Site Space – Put all the information related to your project in one place. This allows everyone to work together instead of emailing back and forth.
Personal space – Store everything you're working on individually, keep your to-do lists, and polish any content before you move it into another shared space.
My space - Only the spaces you marked with a star on the right
Visit the space directory – To get to the space directory, click Spaces in the Confluence sidebar.
Choose the spaces you'll use the most – No doubt there'll be a space or two that you'll use on a regular basis. Click the star to the right of a space to make it appear under My Spaces in the Confluence sidebar.
Choose space categories – Once you're there, you'll see a list of all the spaces in your Confluence site. Choose the 'My Spaces' category on the left to see only the spaces you marked with a star. Then choose all spaces again.
Filter the list of spaces – Type part of a space name in the Filter field at the top right. That'll quickly narrow down the list of spaces if there are a lot of them.
