It was confusing enough the first time I tried...and failed miserably, to articulate it. Suffice it to say, when I'm on a thread, my green back arrow won't let me back up to where I started on the main list of stories, where I chose a topic to discuss in the first place.
There, now are you confused as well?
You have a green arrow? What does it do?
Just kidding... thank you for initiating a very entertaining thread!
