I'm not sure what the question is but I'll take a stab at it. I don't let a little thing like not knowing much about a topic keep me from forming a strong opinion about it. *grin*
When one begins a thread, or replies to an open one for that matter, where it says new "yes or no" it will say no to the author. To everyone else it will read "yes". Whomever made the last post will see "No" until someone else adds something.
It is assumed the thread starter or last one to post already knows what they posted so it would not be new to them. The next post, by someone else, would be new to the author of the last post and would be marked "Yes".
