These may be dumb questions to some, but it will help me understand this behemoth.
1. If I want to modify an action, I need to remove the existing action before adding a new action. True or False?
2. If I want to modify a filter, I need to remove the existing filter before adding a new filter. True or False? (If true, how do I remove a filter?)
3. If I want to modify category.php, all I need to do is copy it from the thematic folder into my child theme folder and edit away. When the theme runs it will find the modified category.php file to use. True or False?
