Portal activity can vary widely and portal users may have very different needs when it comes to engaging with ideas and receiving notifications.
Provide a better portal user experience and keep engagement relevant
Allow the portal admin to set the default frequency for the "weekly" summary email: daily, weekly, monthly
A portal user can override the frequency in their profile settings
The "Weekly summary email" is now the "Activity summary email" and you can choose how often it is sent based on the needs of your audience. Go to Portal settings > Emails > Activity summary email, and select a Frequency. Portal users can override this in their portal profiles if they prefer to receive the email more of less frequently.
