We’ve had a problem in the forums since Dec 17th. Our mailhost has been refusing to send emails from the forum because we have too many invalid email addresses among our user email addresses. The practical result of that is that no one can get a new password mailed to them if they want to change their forum password. Also new users can not join the forum.
Currently working through the 1,170 undeliverable email addresses and putting those accounts on hold temporarily so we can get mail working again. Most people won’t notice any change. To those who did, or those who will, I apologize for the break in service. Normal service will resume as soon as possible.
