Tresler's Rules of Drupal
An ever growing list:
- If you ever hard code a nid into a module, STOP, you are doing it wrong.
- Thou shalt not output html without a theme function
- If you ever write db_query in a .tpl.php file, STOP, you are doing it wrong
- Don't make a view with one node just so you can make it a block. Just make a block.
