Can you "stop publishing" a previously published worksheet?
As a new user, I thought (but am not sure) I saw a page offer to stop publishing a worksheet but now can't find any reference to that in the documentation or elsewhere. This TRAC entry mentions "stop publishing" and is marked as fixed: http://trac.sagemath.org/sage_trac/ticket/3240
Is this possible?
Can you safely just go into the filesystem and remove ...sagenb/home/pub/n ?
