62,000 inspectors registered to use InterNACHI's inspection message board.

62,000 inspectors took the time to register to use InterNACHI’s inspection message board. Together they have made more than 1.6 million posts.

So how did you make the determination between ‘inspectors’ and ‘non-inspectors’ that have registered to use InterNACHI’s inspection message board? If there are 62,000 inspectors, how many non-inspectors are there? If you know one, then you must know the other.

Nice!
