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.
Last, and most certainly not least is the guy who had his name plastered in the background of all the other video announcements.
I have had several video segments from an event on Mackinac Island with candidates in a fundraiser. The Madison Project PAC, and Jack Hoogendyk have been seeking REAL Republicans to support for legislative positions, and much like our $100 project are supportive of primary efforts that bring conservative values into play.
Gary Glenn, who shepherded Right To Work in Idaho in 1985, and has been a stalwart supporter/participant of Michigan's effort is looking to gain Michigan's 98th district house seat. Gary wrapped up the "pickle bucket" stump round up on the island in this clip.
