Click on the Forum title, e.g. on the "Forums by Category" page, to read a sequence of postings to the Forum and its threads all in one page. If you are only interested in one thread or the thread following a specific posting, click the thread or the posting, which takes you to a smaller page, which contains only the part you are interested in and may be easier to navigate.
Messages are "chained" if there are only replies at the first level, i.e. 1/1.html, 1/1/1.html etc. In case of "chained" messages the message number is replaced by the icon and there is no indentation.

The terminology differs between Nuclear Physics and High Energy Physics.
NP says "history" (c.f. MCNP, SCALE) where HEP says "event" (c.f. Geant4, Root).
In HEP and Geant4, generally there is a single primary particle per event, so event = history. Generating multiple primary particles in a single event is unusual, because those primary particles will interact independently, and the term "event" is intended to represent what happens to one of them. But if you do that, then what you say is the closest translation between these terms.
