The transition from the old format was more challenging when starting at the main page. But if I go to current site as dave44 suggests, direct to forum, then it’s about the same.
But i know others used the old main page to get to specific subtopics, and that seemed to be harder to find what you wanted after the transition.
Depending on my screen size and browser, the current main website does not always show the option for forum. But if I expanded window I could see it. Easy once I figured it out. Or better to bookmark it to go direct !
