Purpose

To disable personal pages from being shown in the dashboard, one will need to customize the recently updated content macro by giving it a different parameter.

Solution

This solution is only available for Confluence 5.0 to Confluence 5.8.  

Here's how:

1. Login as an admin and go to your Confluence administration console
2. Under the "Look and Feel" menu, click on "Layouts" (or type this in your browser: http://yourConfluenceURL.com/admin/listdecorators.action)
3. Under "Site Layouts" look for "Global Layouts" and choose "Create Custom"

4. In the layout editor, look for this line:

   $helper.renderConfluenceMacro("{recently-updated:dashboard|showProfilePic=true}")
   

5. Enter the list of space that is allowed to shows up by inserting the SpaceKey in the line:

   $helper.renderConfluenceMacro("{recently-updated:spaces=SpaceKey1,SpaceKey2|showProfilePic=true}")
   

   If you have numerous global spaces, it would be more convenient to use @global instead of listing each space separately. See RecentlyUpdatedMacro-Parameters for the list of parameters avaliable for the function.

6. Save
