Incorrect email address in Yahoo posts

When a user sends an email to the Yahoo groups we get their email address. This is helpful if we need to contact them offline for sensitive data or for very specific topics that would otherwise clutter the groups. With this new forum when a user enters a post via the forum the email address shown in the email that is mirrored to the Yahoo groups is This makes it impossible to get with someone offline without clogging the groups with messages asking for someone to contact me offline. I am not sure if anything can be done, but I’ll bring it up just in case as the old method is preferred.
