Extension:DeleteOwn

The DeleteOwn extension add a user right deleteown which, if granted, allows users to delete pages that they authored, are the only editor on (excluding minor and bot edits), and have not been moved to another namespace. Also, a configuration option allows this permission to expire, i.e., after the page reaches a certain age the author cannot delete it, even if they are still the only editor.

$wgDeleteOwnExpiry

 * Sets how young (in seconds) a page must be for the author to still be able to delete it if they are the only editor. The value can be an integer, which is applied to all pages, or an array mapping namespaces to expiries. Using a value of 0 (or if a namespace is left out of the array in the latter case) has the effect of disabling the expiry.
