Rule 3.1 of the global WWFF rules is very clear:-
“The WWFF program commenced in November 2012. However,
qualifying logs from activations preceding this date can be provided for upload to Logsearch dating back to 30th June 2008”.
Version 5.0 of the WWFF rules was released on 1st December 2016. Rule 3.1 is contained within those rules and came into effect on that date.
Any logs in the system prior to this date will remain there.
