Try this:
In the top left corner of this page, under the Austin Logo in the light grey bar, you will see something called "User CP" [Control Panel]. CLICK THIS
Then on the left, you'll see a long menu of things you can do, but scroll down until you see "Subscribed Threads". CLICK THIS
This will display all the stuff you are subscribed to, which simply means that you'll get an email when anything is updated.
There is a cool link that says "Remove all Subscriptions" and I hope this solves your issue.
If you cannot see this link to remove all, then you'll need real expert help, as mentioned above.
