Hi totally new to Drupal and I've managed to set everything up I needed to. Custom content types, taxonomies etc.
Firstly I'd like to know how to link to a page which will display all the posts in my custom content type.
If you're wanting to build "lists" of things then I would check out the Views module. You will create a new content view and filter by the new content type. If you're struggling building a View just google for 'drupal views tutorials' and there will be a ton to show you how to build things with views.
