Is there a way to edit the activity stream in such a way that will allow supporters to remain anonymous?
I'm using a feedback page to allow dialogue without giving supporters access to the Dashboard and would like the activity feed to not include the names of people who leave feedback.
Sorry for the delayed response!
One option would be to edit the _pages_show_activity_stream.html templates for your custom theme to remove specific signups' names. (Pictured below.)
