Hi Cathie

To begin a new thread in any forum what you need to do is to click on the "New Thread" icon (top LHS of the front page of the forum).

To do a post in response to a thread started by another member you can click on "Reply" in the post (RHS) that you would like to respond to - this means that your response will include a quote of the post (you can edit this quote).

Alternatively, you can click on "Post Reply" (LHS) and then reply. As you can see from my reply, this does not include a quote from any other posts in the thread.
