By default, your Personal Space in the NCSA wiki is viewable by only the confluence-users group, which for some reason contains only a subset of the people with NCSA wiki accounts. To make it viewable by all NCSA staff:

• Browse to the Home page of your personal space (i.e., https://wiki.ncsa.illinois.edu/display/~username/Home).
• From the Browse menu in the upper right of the page, select Space Admin.
• On the left-hand side of the page, select Permissions from the Security section.
• Click the Edit Permissions button in the Groups section.
• In the Grant permission to box, add the NCSA Staff group. The easiest way is to select the magnifying glass icon to the right of the box, then check the box next to NCSA Staff in the list, then select the Select Group(s) button. Then click the Add button to the right of the box.
• Make sure the View box is selected for NCSA Staff.
• Select the Save All button in the upper right of the page.

If you'd like, you can make your Personal Space world-readable. From the Space Permissions page, select the Edit Permissions button under Anonymous Access and grant View permission to the Anonymous user. Don't forget to Save All!

The permissions on your Personal Space will be the default permissions for your Home page and any child pages you create in your Personal Space.

If you want to restrict access to child pages, you can do it via the "Restrictions" section when editing that page. For more details, see the Page Restrictions section of the Confluence User Guide.
