I asked How do I progress with this death record? and accepted an answer. Since then I have undertaken the great suggestions and while not fully resolved, I have progressed somewhat. Am I able to use the question to report back my results or would this be extra 'chatter'?
I've done that quite often over at Stack Overflow. When I finally solve my problem, or find a better solution, I go back and add a followup to my question.
See, for example this question, where I later added an "edit" and then finally a "conclusion".
It is what makes a question complete. You get the question, a number of answers, an accepted answer, and the final reasoning/thoughts of the person who originally asked the question.
It should not be used to restart the conversation, but just to complete it.
