How to remove author name from blog post url?
For Drupal 6; you can go to admin/build/path/pathauto page and change URL alias pattern for Blog content type (under Node paths settings).

You can make it blogs/[title-raw] or anything else you want.



Note: The picture above shows how to do change URL pattern. But, the URL pattern isn't what you want. The URL here something like that: term/blog-post-13.html.
