Together, they have made more than 1.7 million posts.
Are there really 71,000 inspectors?
Sounds like fake news.
If there are (which I highly doubt) that means there are more than 50,000 that do not belong to InterNACHI.
I demand someone call each and every one of them to qualify whether they are inspectors or not.
I agree Paul, I doubt they are all Inspectors. 
No. But more than 71,000 inspectors registered for this message board since it opened on August 4, 2002.
Correct. Most inspectors don’t last 15+ years so I would assume that most are no longer members.
They are almost all inspectors. Very rarely does a non-inspector take the time and trouble to register to use an inspection message board. There are a few exceptions such as vendors, but nearly all 71,000 were inspectors.
10k plus in Florida alone.
