[Mediawiki-l] Email (optional): Enables people....

[Graeme Canivet]

Hi again,
 
I can't find information on this feature. It seems like it is implemented,
but I can't find it. 
 
On the user preferences page it says:
*Email (optional): Enables people to contact you through the website without
you having to reveal your email address to them, and it can be used to send
you a new password if you forget it.
 
When I click on a user, their corresponding User:Page shows up. Where can I
email them using the wiki interface?
 
Thank you,
Graeme.
