### What Happened Higher Logic Online Communities users receive an informational “following” email when other users contribute to message threads that they’ve initiated or to which they’ve responded, to inform them of new discussion on the message thread. Members in some Online Communities received these “following” emails for message threads to which they had not contributed, including for communities they were not members of. **Root Cause** We incorrectly updated SQL query criteria used to determine recipients of following emails.
