I use my blog casually to post things as the mood strikes me. I would like to have the author's name and the date of publication automatically generated for new blog posts and articles on fixed pages.
How do I do this?
WordPress posts by default automatically show the date and author meta info -- unless your theme specifically hides this information or you have a plugin that modifies this standard behavior.
Does your theme have an options panel that may have a feature to hide this info selected?
Pages by default are not dated as they are generally used for information that rarely changes. For pages you can manually add the date at the top of each page if you wish.
