Q: On almost every page i see those small square "-" and "+" icons. What are they good for or what do they indicate?
A: I guess you are referring to the "upshrink" icons
and
.
These icons appear according to your configuration and where the Admins have made them available.
They serve to hide or show content so that you can configure your pesonal layout of every page and they work as a toggle:
Let´s say you are not interested to follow the "Non-Military Discussions & Info" section (#8) on the forum page, click in the
icon right in front of the "8" and this section will be hidden (and at the same time the icon changes to
: A click in this one will show the sectioin again).
There are several areas where you can personalize your layout: In the header section (you can hide your avatar if you have a small screen and don´t like to scroll), the "Home" page (you can hide or show left or right column there), the "Forum" page (you can hide or show most of the sections), and so on.
Hope that helps,
