Thanks everyone, but the member number is like an odometer that rolls forward when people join and rolls backwards when I prune inactive member accounts. I have not done much pruning since 2012, but I used to do it extensively before that year because I was charged each month, in part, based on the number of members. There's a percentage of people who join but never post, and if they've not visited for a year or more, I used to delete those accounts in order to save money but also to make available their usernames so that new Tom's, Dick's, Harry's, and Joan's could join and use their actual name. As a result, the member number goes down after pruning. I pruned thousands of accounts between 2000 and 2012, so who knows what the real member number would be had I not done that.
