I'm glad that you enjoy it. To display the author name, the options are defined under the [Options] tab. The ones that you saw under the Blog or Web Pages configuration are applicable when you create a new item and/or if you want to reset the options by clicking "Reset all item options". The options can be customized per item/category.
1. Item Options
- at the bottom, it shows the author and a link to the user profile
You can toggle this by clicking the "Display created by" checkbox under Options - Item Options (screenshot: cms_item_options_1.jpg) when you edit the item (blog/webpage).
2. Category Options
We usually turn this off, but you can also turn it on when you click Edit Category/Edit Current Category
Sample: see screenshot cms_category_child_item_listing_options_1.jpg
3. To customize it further, click Macros - displayarticlemeta
See screenshot - macro_manager_display_createdby.jpg
Please let me know if you need more info or if you found a bug in these options.
