should there be any concern to our email/password security?
You should be concerned if you use the same password here that you use on other, more important, sites (like your email, your bank, or your work) See http://www.microsoft.com/security/online-privacy/passwords-create.aspx Although CMU does not agree on one point. CMU’s research says that long passwords are strong – but that they do not need to be complex. Could be a phrase from a favorite song or poem.
Use different USERIDs and passwords on different accounts – particularly where the accounts are sensitive.
