I give you a link to your personal Perlmonks Account Disable Page. You get to choose
there what information remains and what information gets deleted. You also get to enter the text that will be displayed during your indeterminate leave of absence.
The button is at the bottom of the page, labeled "Stumbit", as is a Monastery tradition.
As a precautionary measure, to permanently disable your account, we require you to enter a "security code" into the field labeled "password". The current security code is 0.
