Hello, not sure if this is the right place but I hope it is!
I have noticed that fairly often, new posters will post a message about their own problem in a thread started by another mner. Because the thread generally has discussion about the original post, the new post can be overlooked or ignored, which can be offputting to new members and/or cause confusion in the existing thread.
I realise some of the time this is caused because the new posters are unfamiliar with internet message boards, but I have a feeling that to some new users, the thing that might be misleading them is that when you are viewing a thread, at the top of that thread is a link "Add a message within 'Pregnancy'" (Or whatever the topic name is). When you click on the link it takes you to the bottom of the page to the box where you can add a post to the current thread, not the main pregnancy topic (or whichever topic). It's easy to mistake this for a box to write out a new thread - I've nearly been caught out myself and I have been using message boards for years. I think it would be easier for the new user to understand if it read "Add a message to this discussion" or something.
