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.

Photons do have an effective "range," referred to as the "radiation length" when passing through material. It is e-folding distance for attenuation of a beam. You're quite right that some photons will travel many many radiation lengths.
