I wonder if it could have something to do with the members with zero posts. I think Karen and Paul have done a few clean-ups over the years.

I'm sure we'll get an explanation.

Oh, and have you seen how many are "really active"? Like the ones who post frequently = more than once a week.

Btw, by clicking Community and Member list, I don't see the 19,901 members anywhere. I have no option to click only Members there.
