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.

|2||3||2||3 levels / 2 levels|
|3||3||All||3 levels / all levels (all postings)|

In TestEm11, we try to demonstrate that dose profile is the same with StepMax (run01.mac) and replica (run02.mac)
