Here's a quick check to ensure that your SUMMIT profile settings are as you want them.

• After logging on, click/tap on My Settings
• Scroll down to My Notifications - here you can see the emails that have been sent to you. Click on the email to read its message
• Are your email preferences enabled?   Click/tap on Email Preferences.  If emails are turned on, the sliders next to the type of email will be green;  if the slider is orange, emails have been turned off.  Merely put the slider on the right to turn on emails.
