Important Notice About "Phishing"

Some subscribers to the MMS member email service,, have received messages from entities pretending to be the MMS. These emails state that you must validate your account online. These are known in the industry as "phishing" emails.

Unless you are expecting an email from MMS to reset your website password, be VERY SUSPICIOUS of emails that ask you to validate your username, password, or other account information.
