Currently, for a public blog where many users contribute, if you go to the Recent Bloggers portlet you will see a list of all users that have written blog posts and tne number of articles they have contributed.

However if you click on any of the user, the blog portlet will only show the last blog post written by the user.

This should be modified such that when you select any user in the recent bloggers portlet, all the posts that user has written is shown.

Note: this currently happens for private blog posts. We just need to add this functionality to public blogs
