How do I logout?

Left-click on your photo icon, top right for LogOut from a PC.

From a mobile:

"The logout link is in the list that appears when you click the menu icon
at the upper-left of any mobile page.

If you're clicking that icon but nothing appears, we noticed the same
issue. Fortunately, it did not last. If this is happening to you, try
refreshing the page a couple of times. We suspect that the new site
might not sync up or clear the cache right away, but refreshing does
the trick."
