That's good. Of course, just like with the email notification, there is a temporary solution in leaving at least one connected page open all the time.
I would hope that someone using a public computer would remember to sign out, but that doesn't always happen, of course, and we've all got other things on our mind at any given point. There are advantages and disadvatanges with either, of course.
Still, though, the new site is starting to grow on me. It'll take some getting used to, but think about how many sites we go to that have changed over the years and we have eventually gotten used to those changes.
Progress never stops.
