We have been sending out a variety of email notifications to both those that are registered, and those that have just signed up for the email Updates. A few people have complained of not receiving some of these Updates, but when we look into the history of the messages, we invariably find that they were sent successfully to the email address on record, but the person never opened them. The most usual cause of this is some sort of SPAM filter or other email filtering mechanism. If you are using this type of email filtering, Please keep an eye on your junk mail folders for our messages. There is nothing that we can do about the problem. All that we can do is to try our very best to ensure that the emails are delivered without "bouncing back". After that, they are at the mercy of the recipient's email system. All messages that do get returned as "undeliverable" are followed up as best we can with NMRA HQ to try to get a valid email.
So, please check your junk mail frequently, and if you do change your email address, please send the new one it to at least the registrar, and preferably the webmaster as well.
