The idea is that you don't know the addresses of people, since people over the years have gotten trouble with spam when their addresses are known.
You can either answer on the forums or if they have e-mail next to their name you can send to them but you will not know their address since it goes through Curezone.
They will know your address when it arrives but if they don't write back you will never know their address.

The idea is to use the forums so everybody can learn from the questions and answers. There are many different ways of getting healthy so everyone should read as much as they can so they can find the protocol they want to follow.
