Please note that it is now possible to contact each other via email.
Simply view the profile of the person you wish to contact and select the 'Email User' tab. You can then send them a message directly.
Rest assured that no email addresses are revealed and all communications are done directly via the website server. If you receive an email and do not wish to reveal your email address to the sender but do want to reply, then you can also use the same 'Email User' facility on their profile.
