You can remove demo pages that are informative. What shouldn’t be remove it this:
Login, Register (if users login to save favorite properties)
My Profile, Favorites (for the same reason – save favorite properties)
My properties and Add new listing pages (if you have the option to allow users to submit properties)
Payment Processor template – if your have one of the payment systems enabled.
Does this imply that certain functionalities of the theme are dependent upon the above listed page setups? Meaning, to avoid difficulties in creating new setups, we should use these, or face difficulties?
