How can people have their email address visible for other members? I cannot see anyone's email address in their profiles, and I can't even make my own email address visible.
I just dug into the configuration and figured it out. You should now be able to send e-mail to those users that wish to receive e-mail from other users. To receive e-mail from other users, go to your User Control Panel, then "Edit Options". There is a check box to "receive e-mail from other users".
I also setup the default option so that everyone will initially allow e-mail.
