Question:
"I get an email notification on every thread. I see how to subscribe but not how to un-subscribe. HELP"


Answer:
In the "My Controls" section on the left there is a category heading called "Subscriptions". Underneath that are "View Topics" and "View Forums" links.
Like so:


Check the forums/threads you want to unsubscribe from and click the "with selected" button.

That reminds me of the time Andy had to splain to me why all of a sudden I was getting ALL the threads in my email notification. I picked FORUM instead of thread. Duh
