Tom Are you having more issues? In case it helps you (and others to access the forums), the ONLY way I've gotten into these forums is through browser history in the Back functionality. For example, let's say I want to enter Beginner Questions, I access that URL and it fails, then I try to access the main forums and it fails, but I can use the Back functionality in the browser, and suddenly, the initial failed path works fine. Presumably because it was cached?
EDIT: Posts are working now, guess you're getting things under control, .
