The latest addition to the Free Setup Utilities page lets you do just that.

- New page: How to Change the Background Colour of a Web Page in CSS (HTML/CSS).

- New page: How to Block the Author ID and Author Archive URLs in WordPress Blogs Using .htaccess. I was asked by a visitor how he could block queries for his author ID and archive pages on his WordPress blog using the Apache .htaccess file.

This article answers that question, as well as provides additional things that need to be done if either or both those reasons were behind the query.
