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 ?
I had a related problem by publishing a worksheet that was accessible by the url 'https://<srv_address>/home/pub/13', then deleting the worksheet and emptying the trash. The worksheet stayed among the published documents, and was "owned" by 'pub'. I had no mean to remove it by the notebook menus or commands. Publishing a worksheet created a new directory named '13' in a directory named 'pub' in the directory structure of the notebook ('/home/sagemath/.sage/sage_notebook.sagenb/home/__store__/3/3a/3a2/3a21/pub/13' in my installation). Recursively removing '13' from 'pub' succeeded to remove the worksheet from the list of published documents, but only temporarily. The file comes back in the list of 'published worksheet' after a while. Someone knows how to definitely remove it?
