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.

Firstly, the Geant4 General Particle Source (G4GPS) class is quite powerful, and is a much more straightforward way of implementing histograms in energy, position, angle, etc.
You can read up on all the commands available if you search for "gps" in the user manual (book for application dev, starting page 28 of 385). Additionally, examples can be found under: <geant4dir>\examples\extended\eventgenerator\exgps\
As far as your renormalization value, I assume this is so that you can use multiple sources, with different normalized spectra, and of different intensity (and hence scalefactor)?
If this is true, you may also achieve this in G4gps, by changing the intensity of the source when adding multiple ones, through the command
