I would like to propose a change in the way people ask for Help on a puzzle and then insist that the answer be without guessing.
From now on, no one answers such a request unless the person making the request specifies which techniques he/she considers acceptable.
You don't have to agree with the requester's list, you simply limit your reply to those techniques ... period!!!
This should end a lot of bickering that seems to occur.
Maybe this could even be made part of the Sticky on how to ask for help!
