I've learned that in Confluence Server, you can see a page of contact information for your admins by going to:
http://[Confluence-URL]/contactadministrators.action
1) The fact that this was explained in the Community pages means that more people would really like to have know this. Can't you put the link in the Help menu or something?
2) Can you make the same page available in Confluence Cloud and Jira?
One can also send a message to one's Jira admins through the form at:
http://[yoursite].atlassian.net/jira/contact-administrator
3) Can you add this to the Help menu?
4) Can Confluence get something like this too?
