After the moderator election I clicked through the newly discovered user tabs and I found a little inaccuracy.
The tool tip of the tab says users who joined in the last 45 days. As it happens I am a 46 day site member. Yet I am still listed in the tab. Of course, this is not a big thing, I just thought to mention it anyways.
EDIT: Since the time zone might be relevant. I am currently within the UTC + 1 time zone. I noticed and took the screenshot at around 10:30.
