It might be somewhere else in the thread, but can someone clarify if these things are "one off" (unless you upgrade your VFF status from Gold to Platinum, giving you a different set of statuses to be entitled to)?
For example, if I keep maintaining my VFF Platinum every year, will I be entitled to 6 months of HH Diamond after each review?
What if I don't keep VFF Platinum (drop that status and lose my HH Diamond as well), then another year down the track I manage to get VFF Platinum again - do I get another bite of HH Diamond cherry?
The T&Cs don't make this too clear, and from reading it it seems that you will be "cut adrift" as it were after the VFF "sponsored" (so to speak) period of membership is over, leaving you to requalify however the partner intends you to do it.
