BuddyPress.org

slightly confused by the request. WP 3.0 has the capability to allow user blogs as either sub domains or directories, would that achieve your request? failing that you can always set users as ‘Authors’ on the main blog which would allow them to create posts. Simply creating a page and naming it what you like will do nothing as that is simply a ‘Page’ on the main blog and requires content added via the dashboard when you create that page or content/scripting added directly to a file named as that page and set as a template.
