User updated his email address in his profile, but comment notifications in the forums are going to his older email address.
This was an issue with the pre-Kenai processing. When we were using CollabNet we were trying to keep the user profile updated on both systems and there must have been some issues. Now we are setting the user email address to <username>@java.net for all new users and never cahnging it so all emails should be sent to that alias which should forward to the correct email address that is stored in Kenai.
There could be some more issues that exist and we can update the email address on a case by case basis.
Updated Tom's email address to <username>@java.net (firstname.lastname@example.org)
