Cool! I tested it and it works. If you hide all of them, it still shows the horizontal lines which looks a bit weird.
Just a note that this is just a visual change. The numbers are still accessible to those who know how to find them.
Curious to understand why you would want to hide that row of stats? They give an excellent summary about your site that members and potential members will like to know. Is it one or more of these numbers in particular that is concerning you? If so, which one or which ones?
I did notice that the “0 moderators” looks a bit weird. Maybe we just change it so it is not shown if there are no moderators.
@Don do you know if you can use CSS to change the “Created x years ago” number?
