[xwiki-users] panel viewable by unregistered guest?

Hi, I'm new to Xwiki and am using an Xwiki Enterprise 1.7.2 with multiple spaces. I just migrated this wiki from another organization that was using version 1.4.2 (in case that makes a difference in my question). Environment: apache centos 5.2/tomcat 6/mysql 5.1 - I searched mailing lists, google and xwiki site but found no leads yet. The migration went well and now I've added a new public space. The wiki as a whole denies all rights except 'Register' for unregistered users. But the new space grants 'View' access to unregistered users. View access is working fine *except* none of the panels appear for unregistered users and I wanted at least one to show by default - the one that lists all the pages in the space. how can I let unregistered users see this without logging in? Thanks, Cris
