How to display Newsletter option in Magento

You can also do this with a static block in the back end with out going near the app code.  I think it is better to do it this way incase a Magento or an extension update overrides the edit. From the admin/backend of your store go to "CMS" nav menu at the top & select "Static Blocks".  Click on "Add New" button. In the subsequent form give a unique name to the "Block Title" &  "Identifier" & make sure it's status is set to enabled. Put the following code into the "Content" text area... {{block type="newsletter/subscribe" name="left.newsletter"  template="newsletter/subscribe.phtml"}} Take note of the name you entered for the "Identifier" as you will need that in the next step. Click on the "Save Block" button.
