From what I understand you can't kick or block or ban anyone from an artdesk canvas if they're not online. Little bit concerned about myself going offline, coming back to some artwork that shouldnt be there,... while I can delete it myself, that's awesome, it does no justice if that person is offline by the time I get to it. On that note we also can't give/remove admin perms to those that are not online. Can these features be added?
