Portal Server provides a blog portlet that uses the Atom Publishing Protocol (APP), the standard protocol for managing weblog posts. The portlet enables portal users to publish weblogs from a portal page. End users can perform the following tasks:
Create weblogs
Create, edit, and delete blog entries
Create blog server user accounts
The blog portlet provides a simplified user interface. For more information, see the Managing Sun Java Systems Portal Server 7.1 Blog Portlet.
