This is about a possible, but minor, bug.
I noticed this note at the bottom of an email from GKS that I got today (8/3/23):

I had been off the site for about 3 months but was on again about a week ago (7/27/23). I’m just letting you know in case there’s a bug in detecting absences, though it’s not a big problem really.
Thanks for all your hard work. Really like the site.
