 	* UserWorkflow.cpp (UserWorkflow::report): see #1466 Implemented
 	instrumentation that should help us improve user experience. Will
-	track few things that new users do (or don't) and report as a
-	combination of bit flags at the end of the GUI session. Reporting
-	things such as if user looked at "Getting Started" tutorial, if
-	they created their first firewall object, modified any rules,
-	tried to compile or install. Information passed in the report is
-	strictly a set of boolean flags, is not identifiable and does not
-	reveal what firewall platform they are using or anything about
-	their objects and rules.
