How to delete a Switter account

Now that I know more about Switter, I want to delete some accounts and start over. I cannot find any way to delete the account. Can someone tell me how to do it?

Go to Security and scroll down to Delete account. If the delete account link is not there, the function has been disabled by Switter (there are reasons to do that, sometimes), in which case find the Switter contact e-mail on their /about/more page and send them an e-mail with deletion request.
