Thread:Project:Support desk/Not able to set permissions on page

I have got 2 Namespaces. In 1 namespace I wanted to have restricted access i.e page should not be editable without the person logged in. It is working fine(thanks to help from this forum only). Now I want to have the Main Page (in the 2nd name space) be accessible as readonly to all and only selective group be able to edit this main Page. Will appreciate if I can get some help here.
