The primary security measure is that the email address, home address, and other contact information of a member is NEVER provided to the public. When you send an email inquiring about visiting or exchanging a home, the recipient will see your email address so they can reply, but you won't know their email address until you receive a reply. NO OTHER INFORMATION is ever provided to members. It is solely up to our members to exchange address and other contact information through their own private communications.
