I've noticed that some blog contributors are able to remove the "author bio" box from the end of their post. I'm not sure how they have done this because they are not admins in the blog. For example, this post and this post do not have an author bio and their bio is tacked in on the end of their post. While this post DOES have an author box.
How does one remove the author box if you are not an admin? Is there a way to do it by adding html code?
I'm kind of a newbie so please don't be too technical in your answer.
The blog I need help with is alonothing.wordpress.com.
