Edit links inside My Account page via xml files

The Magento account page is the screen shown to the user after login.
In this page there is a menu with various items.

Depending on the website, not all the items presents in the menu are useful, some of them could confuse the customer.
By default the items presents in the menu are:
  1. Account Dashboard
  2. Account Information
  3. Address Book
  4. My Orders
  5. Billing Agreements
  6. Recurring Profiles
  7. My Product Reviews
  8. My Tags
  9. My Wishlist
  10. My Downloadable Products
  11. Newsletter Subscriptions
Magento doesn't implement directly in the administration backend a manager for this type of editing, so we have to edit the source files.
WARNING: the Magento layout edits are saved in the CMS cache, remember to refresh the Magento cache after every edit (or disable the cache temporally).

A little tip before the end

If some functions aren't used at all in your website, more than hiding only a menu item, it's better to directly disable this function. As example if you're sure that the function Tag will not be used, you could disalbe it going on System -> Configuration -> Advanced and disabling the Mage_Tag module.
