That's right Nillers. This is the advice from page one of this thread
REPLY BY WEBMASTER - 13 Oct 2008:
On sign-up, your email is now hidden by default. Only you and the admin can see your own email. A small envelope icon will be visible to you but NOT to anyone else.
As a security update, since 11 Oct 2008 when all email addresses were hidden forum-wide, you will only be able to see other emails if the user has specifically gone into their account and unchecked the 'hide email' box.
Of course since this was posted Emma has removed the small envelope as she says in her post a little while ago.
