I assume that you want to hide them away from Admins of your site. Then the easiest way is to install the free TRT Control Panel (davebuckner.com). This Control Panel can restrict modules and tabs for Portal's Admin.

Alternatively, you can still hide the pages away from Admin by editing the Database. I'm not sure how, but this might give you a hint:

<tabpermissions>
        <permission>
          <permissioncode>SYSTEM_TAB</permissioncode>
          <permissionkey>VIEW</permissionkey>
          <rolename>Administrators</rolename>
          <allowaccess>false</allowaccess>
        </permission>
</tabpermissions>

Is there an estimated release date for DNN 5.0?

Thanks.
