It occurred to me that some type of questions might require intermediate steps, trial and errors and other similar back and forth mechanism.
The general consensus is that back and forth in the comment section is a no-no in the EE.SE best practices. But, the chat function of SE is perfect to take care of the back and forth.
My question is this, should there be an explicit guidline regarding that type of interaction in order to have them without actually disturbing the concise nature of our questions and answers format?
My first stab would be that the OP and OA go to the chat for the back and forth and once new information comes in, the OA update the answer. Any thoughts on that?
