WordPress as a very nice Author-info, I like it. By default it is off unless there are more then one author post on your blog. You can turn it on without installing any stupid plugin or code edit. Follow these steps.
- First you should update description in your WordPress user profile
- Open phpmyadmin or equivalent.
- Open your WordPress database.
- Navigate to table
- Search for
option_namefield for value
- Set this value to 1 (for true)
