Melinda and Glenn,
To unsubscribe, click on "My Profile" and then click on "Forum Subscriptions". Now you should see the following: "Subscriptions", "Subject", and "Forum Name". Delete each posting under these headings.
Then the next time you post to any of these forums, be sure to un-check "Check this if you would like to be notified when someone replies".
Jamie, I think it would be better for most of us if the default was "Un-checked" instead of us having to remember to un-check before submitting.
