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.

This was discussed in the Release Notes.
It's bad form (though found throughout older G4 code!) to rely on headers including other headers. It can cause side effects, increases unnecessary dependencies (so that code has to be recompiled even when it shouldn't need to be) and obscures the true dependencies of code.
These headers were removed from globals.hh, so that .cc files which actually do need to make use of either constants or units would explicitly #include whichever of those files they need.
