I am trying to create a smart group for contacts that have activity added by specific person.

Advanced search allows me to search either (1) for contacts based on some activity; (2) for activities based on who has added the activity.

But unfortunately not for contacts based on who has added the activity.

UPDATE: (Tested on CiviHosting demo site.)

Advanced search parameters:

• Display Results As: Contacts

• Basic Criteria - Complete or Partial Name: Errol

• Activities: (*) Added by

RESULT: Search returns Errol as the only result, not all contacts whose activities have been added by Errol.
