I bought this plugin today and have been testing it on our test site. It is a great solution for anyone who is really serious about creating lots of content. With this plugin, you can create a unique and fully customized author box for each of your posts and/or pages and other post types.

It's really easy to customize all the options you need, and I must say that it has A LOT of options, for everyone, maybe even too much for some... but I always think it's better to have more than less.

Nonetheless, WP Simple Author Box was a very easy plugin to set up, and I was able to add "author boxes" to my test site very quickly. These boxes contain the name of the person who wrote the article, along with a picture and a brief description of the person, as well as any extras you selected (for example, I really liked the following option — a tab with the latest posts by some author).
