Group members have a new opportunity to be more responsive when their
group is @mentioned. Group mentions now trigger push notifications. You’re on the road, with only
a phone to keep you tethered to that vital business you’re on. Now you can count on it to keep
you tuned in to the things that people want your group to be aware of.
This feature is new in all versions of the Salesforce
To be notified about group mentions, members must select Email on every
post under Groups in their Chatter email notifications settings. After notification
is enabled, you can get push notifications on mobile devices by enabling Someone
@mentions your group under Push Notification Settings.
