How do you log off the forum? There is nothing to click.

In the upper right at the very top of the forum window, you'll see your user name on the forum.  Next to it, is a picture of your avatar.  Click on the avatar and you'll find Logout at the bottom of Your Profile.

Thank you!

I learned something, too.  I didn't know where it was before I hunted it down for you by trial and error.
