Your age reduction was accidental. Many put their age back deliberately. I think you are correct when you say less people are accessing forum. You only have to go back through the messages and look at the names. Majority from a small group.
I don't think its just luck that I mostly received a reply from TP Support when I contacted them direct rather than in forum. I could not be that lucky so often.
Best wishes in advance for your 92nd and many more birthdays.
