Track lists things you have posted to. If you want to unsubscribe from things so that you don't get emails when they're posted to, you can do that under the subscriptions tab.
Your miss understanding what she said IMO. Track is all treads you pot in. You can not delete that list it's your post history Use the subscription page for tracking threads you want to keep an eye on.
Gotcha. It's okay. I thought I might be helping out by clearing up space on the server. Some sites only allow me to keep so many e mails and such. Thanks for chiming in.
