<p>Drupal's blog module allows registered users to maintain an online blog or diary. It provides easy-to-write and easy-to-read online diaries or journals that can be filled with daily thoughts, poetry, boneless blabber, spiritual theories, intimate details, valuable experiences, cynical rants, semi-coherent comments, writing experiments, artistic babblings, critics on current facts, fresh insights, diverse dreams, chronicles and mumbling madness available for public consumption.</p>
<p>TODO</p>:
<p>Add an entry on the account display for another user, linked to module.php?mod=blog&name=$userid</p>
<p>Provide links on other "Noded" module displays to allow the node to be blogged module.php?mod=blog&type=blog&id=$nid . Currently these are available on blogs and import displays.</p>
<p>Combine the calendar display class with the node calendar display class.</p>
