Worth posting this, I think. A 'sticky' is a topic which is put at the top of the forum, along with any other 'stickies'. A 'hot topic' has a moving image, not shown here, and means there are quite a few postings; it doesn't mean it has a lot of readers. A 'moved thread' is listed in two places - for example our 'Enola Gay' film material appears in two forums - Hiroshima/Nagasaki, and propaganda films. 'Subforums' look useful, and seem to be a feature of the software, but it's not clear how to generate them.
