Redmine

This is a very good feature request! Indeed, it would be even better if it included custom user fields as well. If you define i.e. a custom user field "cell phone", you most likely wish to allow only users with accounts to see this number - specially when you run Redmine with self-registration disabled.

I second this request. Authenticated users seeing each others email address is fine with our organization because redmine ldap signon and email are tied to one another anyway. But I'd prefer outside users on our public tools could only download distributions and report issues.

This plugin does it nicely: http://www.redmine.org/plugins/hide-emails. The only problem is that you should edit this value for all existing project members.

Maybe, this should be a core feature?
It would be good, to hide e-mail-addresses by default for non-registered users.
