When you use the "quick reply" box where does it get the title for your reply from?
And where does it plug your reply into the discussion tree?
It almost looks to me as though it inherits your comment title from the title on the root of the discussion, but it plugs your response into the top of the subtree that you just read. But I am confused about it.
David, you "got it" exactly.
Two ways to post: quick reply - uses defaults - minimal control over the result.
And yes, it always attaches the new post to the original "first" post of the thread. Correction by JavaMouse: no! Quick Reply is a reply to whichever post is the "starting one" in the sequence that you are viewing. If you see a tree for the entire thread, and you click on a message within that tree, the "Quick Reply" in the next browser screen that comes up will refer to the message that you chose to view as the "target" of the new message.
Click the "Reply" or "Quote" link within a message - full control over the post contents. And determines exactly which existing post becomes the parent.
Titles: Every post in a thread, including the thread's starting post, has its own title. When you leave the "Title" space blank within a thread when posting, or if you use "Quick Reply", the title of your post defaults to "Re: " + the original thread title.
Parentage: as with the old Ezboard, it really matters which reply link you use. Whichever post within which you click "Quote" or "Reply" becomes the parent of your post.
I'm not really thrilled with the concept of the "Quick Reply" message box. What it does is cause some people who aren't tuned into these nuances to reply to the wrong post.
Worst case, if everyone only used Quick Reply, we would have only flat threads.
