In this page you can take a look at all the features available in the JBoss Blog application.
The JBoss Blog application has two main functions:
- aggregating blogs of JBoss employees
- archiving posts
It is not meant to be a blog-authoring application. So you should have an outside blog (on Blogger, Wordpress or wherever), which you use for authoring, and then aggregate it into the feeds system.
Also, when using the application, you'll probably notice a "Tips" box on the right - it often contains description of configuration parameters, explains the meaning of some options etc.
