How do you delete a Stack Exchange account (for a specific site)?

For example, if you committed to a site, and then found out that it's not really what you're looking for.

  How to delete your account:

  Edit your profile to say "please delete me" so we can confirm your ownership of the account.

  Obtain your user page URL or numeric user ID. This is linked from the top of every page of the site, when you are logged in.

  Email the support address linked at the bottom of every web page on the site. Where it says "contact us", click that. In your email, you MUST include your user page URL or user ID so we can find your account.

  I would imagine this will eventually change to some kind of automated process though once it becomes a hassle.
