Deleting a thread because of privacy issues?

Hey, does anyone know how to delete a thread due to privacy issues?
One of my threads has too much private things about me. I’m afraid that people might be able to tell who I am.
Also, how do you make your birthday private?

"Can My Posts Be Deleted?

Posts are editable for a brief period following posting to allow correction of spelling errors, formatting, etc. After that, members may not edit their own posts. This prevents one member from editing an earlier post in a thread, rendering comments by others irrelevant or seemingly inaccurate. Similarly, we cannot delete posts upon request. Doing so would destroy the integrity of our archive and consume a huge amount of manpower. Therefore, please do not post personal data or other information that could prove to be a problem later."

To make your birthday private:

Click on “My Control Panel” (upper left hand corner of page).

Click on “Edit Your Details” (under “Your Porilfe” towards top of page).

Under “Optional Information,” under “Privacy,” select “Hide Age and Date of Birth.”
