To help you figure things out, there is a Scoop Admin Guide which can hopefully answer most of your questions.
Some tips:
Most of the layout is changed in "Blocks", found in the admin tools menu
Features can be turned on and off, and configured, in "Site Controls" in the admin tools menu
Stories have an "edit" link right beside the "Full Story" link on an index page, and right beside the "Post a Comment" link on the full story page. They can also be edited by clicking the story title in the "Story List" admin tool
Boxes are what allow you to write new features for Scoop; they require a knowledge of the perl programming language to work with effectively, although you can often make small changes without knowing much perl. If you would like a feature added but cannot program it yourself, ScoopHost does custom Scoop programming as one of its services.
If you aren't sure where to look for a particular feature or piece of display, try the "Search Admin Tools" link in the admin tools menu.
This very important lesson was imparted to me when I had began driving for a living several decades ago by a wise trucker.
Maybe because I had more co-workers who had more conscience about training me at that time, or they were just superior to the people turning out the "young guns" nowadays, but I understood this axiom very clearly even back then, and over the years, have gained a greater appreciation for it.
It is also a lesson that I found is easily and very applicable outside of trucking.
Am I trying to change the focus over from politics to Trucking?
