Hi – many apologies for the confusing signposting on the Forum. There is a stray ‘scroll down to start a new post’ message at the top of the screens to view a topic or a reply to a topic. I will fix this and make the different forum functions easier to use but it will take a few days as it is not simple (for me).
In the meantime, to answer your question:
To start a new topic first navigate to the Forum where you want to create a topic:
Having ‘clicked on’ your chosen forum title you will see the list of recent topics and there will be a valid ‘Scroll Down. to create a new …’ message at the top of the page.
If you scroll down you will find the form to create a new topic.
