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.
My father, who was old enough to fly P-51D Mustangs for the USAAF during World War 2, can remember exactly where he was and what he was doing when he heard about the Japanese attack on Pearl Harbor. Likewise, my elder brother (the only one of my siblings who is legitimately a baby boomer) can recall exactly where he was and what he was doing when he heard about the assassination of President Kennedy.
In the exact same vein, a certain September morning a decade ago is irremovably burned into my memory.
I really was ready to give the man credit for going after Osama in Pakistan.
I was ready to say congratulations Mr. President, as I give a hearty Hooah! to our troops and special ground forces that apparently snuffed the life of the top radical islamo-terrorist dirt bag. Hooah! to those troops.
But MR President, I am sorry. You had an opportunity to take appropriate credit as you should be able to, but you goofed. You revealed you had no idea of what was going on on. You gave away your indifference.
In your speech you said you gave the order to take him out"today."
But he died last week according to our military leadership.
Update [2011-5-2 7:28:35 by JGillman]: OR did he? It seems the raid that killed him did so in the wee hours of the morning yesterday. This guy even tweeted it while happening. Bizarre.
Ham and eggs and more ham on me Mr. President. I'll save the TOAST for our boys who did the real work.
