Are you talking about like the MSN icon that contains an email address?
Yes, that's correct.
Ok, but this user, just registered with an MSN mail address, I mean I didn't activated any other fields for mail address, and I've tested his profile with a dummy account, I can't see his mail on his profile.
But I can on the who's online.
This is not logic for me, because the user request in his profile to not receive any email from others, and if the who's online reveal it, it's not fair.
In that case the who's online should show all the mails of any members despite of the profile setting...I think.
