Changing Drupal Blog-Entry Settings
Creating your Drupal blog entry probably feels very familiar to you. It's very much the same as creating an article or basic page. If you scroll down the Create Blog entry form, you see the same optional sections:
Menu settings: In general, you should not change the Menu settings. The Blog module creates a specific area where all blogs are stored. Using the Menu Link Title and Parent Item creates a link to just this specific blog entry, not to your entire blog.
Revision Information: If you want to make changes just to this blog entry but want to keep the old version, use Create New Revision.
URL Path settings: Allows you to specify an alternative URL for your blog entry.
Comment settings: Decide whether you want to allow comments, and use these settings accordingly. They apply to just this blog entry, not all.
Authoring Information: Your name and the time and date are automatically populated. If you have several people contributing to the same blog, you can customize each entry here.
Publishing options: These control where this single blog entry will appear.
With the possible exception of Revision Information, it's a bad idea to use these settings very often. Blog entries should be consistent — and when you change the settings for one, you have an entry that no longer fits in with the others. Instead, you should change the overall configuration of your blog.
