I'm surprised there is no ability to simply delete a workflow. Or...am I missing something? I just beginning to learn Nintex workflow, so created a 'sandbox' list to work with as per the 'getting started' exercises here. Something seems to have corrupted the approval task form as I am getting a web part page error message. I'd like to just delete the workflow as opposed to the list and start over. But, for now, in this sandbox, I'm not too concerned if I delete the entire list just so I can delete the workflow. thanks.
