Tester, in the situation when you use "Username" all over the site instead of "Real Name":
- You can create the list manually. Visit each blogger's profile, find out his/her real name. Create a list. Wrap it into html to give a nice look and feel. And then paste into the custom html widget.
- customize software source code heavily, to grab user's real names even though "username" is used site wide. Just using .html will not be enough in this case.
If you are using Real names on your site instead of usernames:
- Customize source code of the "Blogs" widget, which currently is already displaying the list of the latest blogs on the main page ( ow_plugins/blogs/components/blog_widget.php and ow_plugins/blogs/views/components/blog_widget.html).
