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.

It's funny - I was looking into exactly the same thing yesterday! I found this in Section 220.127.116.11 under "Boundary Processes" in the Application Developer's Manual:
"Surface objects ... are stored in a related table and can be retrieved by either specifying the two ordered pairs of physical volumes touching at the surface, or by the logical volume entirely surrounded by this surface. The former is called a border surface while the latter is referred to as the skin surface."
So, my understanding is that a G4LogicalSkinSurface specifies a surface completely surrounding a single detector volume, whereas a G4LogicalBorderSurface specifies the interface surface between 2 detector volumes that are touching.
Hope this helps, Sam
