Because Wikipedia content is licensed under the GFDL and the CC-BY-SA, all edits must be kept for attribution purposes, and so your account cannot be deleted. You do, however, have the right to vanish, which you can exercise by (1) requesting your user page (found at Special:Mypage) and subpages be deleted, by adding the {{db-userreq}} template to them; (2) requesting to change your username to something that is unconnected with you (possibly a random collection of letters and numbers); (3) never logging in to your account again. The "right to vanish" does not mean anyone has the right to a fresh start under a new identity. Anyone who wants to continue editing should request a change of username instead so edits can be reattributed.
Usage
- The resulting text includes no indents, so do not forget to insert a colon (:) before transcluding the template:
:{{HD/vanish}} and not just {{HD/vanish}}.
- The resulting text also does not include a signature, so sign your message as normal using four tildes.
