If you no longer have access to the email used to register then in order to get your password reset start a thread in this forum to request a password reset. I will then update your profile to add the new email address. Once I do that you will be able to reset your password to once again gain full access to the community.
The forum is a secure forum. Only the thread starter and myself can view or reply to the threads.
I am sorry about the inconvenience. This change is for the better to bring this community into the future.
