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.

if you run with tracking/verbose 2, you will understand your ouput (I hope ...). For the second part of the question, please read a minimum of documentation about geant4, or any MC transport code in general ...
