@harish:
Thanks for your time and feedback.
For access denied, since it requires an authenticated user, you will need to create an account. You can use mine - user: nikunj / pass: test if you want and feel free to create your own account on the demo site. To reduce spamming I have kept email verification required.
One of the main purpose of the module is not to add a separate entity and keep all the addresses stored separately. Unlike User addressbook where you want the address to change everywhere if you make change in addressbook, this is more like a utility for content creators to copy data from already submitted addresses. Each address will be stored separately and it won't affect already submitted values/entities.
About giving names to addresses like Home/Office/etc., it will make more sense in scenarios where we are storing it as entity. This is for mainly content oriented sites where address is used for location or more generic purposes and not for shipping and re-using. Current scenario: As an admin I need to create multiple events/jobs/etc. where address is required to allow users to know location of event or job location. It may be in same city but just different buidling or may be same location multiple times. I can copy from existing and change any of the data if required.
Let me know if it still doesn't makes sense.
