There is much, MUCH more on this to be found in the mailing list archives. If you can, please be more specific about how you hope to use E-mail addresses, and generally what you expect to be different (about the operation of your site, and/or the user's interaction with it) if you have that information versus if you do not.<div class="im">
</div></blockquote><div><br>The site I'm working on would use the user's email address for two purposes:<br>
1) To send various notification emails (for example when the user receives a reply to a message)<br>
2) Users can have administrative powers over certain groups. If a user
adds or removes another user from a group he/she is administrating,
then the added/removed user receives an email with the administrator's
email address as a reply-to address.<br><br>So the email address certainly isn't essential for using the site, but is helpful. If it's not possible I need to know so I can make changes to the design documentation accommodating users who we cannot send email notifications to (since certain options won't be availble).<br>

So in the settings it would say something like "email address: contact via OpenID" but would not be able to actually state the email address?<br>

Are you thinking that, to contact a user via E-mail, you would have to contact their OP (perhaps through OAuth) and request that the OP send that user a message on your behalf?<br>
</blockquote><div><br>Yes that was what I was uncertain about. I checked the Facebook Connect <a href="http://www.somethingtoputhere.com/therunaround/">sample application</a> and that is how it <i>appears</i> to work. Do certain OPs withold email addresses and certain OPs make them available?<br>

What if I don't want the *OP* to know my E-mail address, but I'm fine with *you* knowing it?</blockquote><div><br>The user is free to set up an email address and password with my site and not use an OP for logging in.<br>
