Also check in your user control panel. I can't remember what the default setting is, but in 'edit options', the third or forth option down enables you to set the default for thread subscriptions. Set it to 'do not subscribe', scroll to the bottom of the page and save changes.

Now you have control over what threads you are subscribed to, if you don't do this, every post you make will become a subscribed thread.

If you want to delete any subscriptions, just check the box on the RHS and at the bottom of the page select delete in the drop-down box.
