I have JIRA and Greenhopper in the same site: mycompany.atlassian.com
They work very well, but recently i sign up for Confluence. What if I set the access site to mycompany.atlassian.com? It will be integrated with JIRA products and share the same users?
If is possible, is there any change to change my url of my Confluence mycompany2.atlassian.com to the first one?
NOTE: The urls provided above are not valid, just examples.
