What's the change?
Why did we do this?
firstname.lastname@example.org was relevant when we were branded as a developer network/forum. We have evolved much since as a community and we feel it is only fair that the email id should reflect the same.
Impact and next steps for you
If you have already set any rules to move Communities notification emails to designated folders in your mail client, you'll need to edit and update those rules with the new email id email@example.com. Otherwise all notification emails will reach your main inbox, which is its default destination.
No change other than the sender mail id was done from BMC end. You can still participate in conversations easily by replying to the notification emails.
