Since most of the administration is self explanitory I will only get into the 
details of how some functions work.

Latest Listings
The Latest Listings are the last #?? of listings you have added to the database.
Set the number of items per page in the admin program.

Featured Listings
Featured Listings can be set to always be at the top of the category page.

The rotation of the featured listings in the RIGHT COLUMN works like this:
You set the number of featured listings to print on the admin page.
If a user clicks on a category that has featured listings in it, the program
will print the featureds from that category at the top in random order. If
the number of featured listings in that category is less than the number you have set,
the program will go through all of the listings and find the remaining to print from ALL
featured listings, also in random order.

Sudo Banner Rotation
Basically works the same way as above. The program looks for something in THE category
first, if not found, it will print one from ALL the featureds in random order.

If you choose to rotate TEXT as well in the Banner Rotation, they will be rotated
in random order and are treated just like a featured listing.

Featured Listing Link on Page Top
If you have the featured listings in the right column, it would be redundant to 
show the featured listing link in your page top.

Short Description
If you have a small number of items you can have your entire cart on the main
category page. Just put the full description in the short description area of
the form. You can use a larger thumbnail image on the page. Set the thumbnail 
image width in the admin program.
The details page will still be there for larger images.

Image Names
The naming conventions are as follows:
thumbnail image: item_number-t(.gif or .jpg or .png)
1st image on details page: item_number(.gif or .jpg or .png)
2nd image on details page: item_number-2(.gif or .jpg or .png)
3rd image on details page: item_number-3(.gif or .jpg or .png)

The images on the details page are clickable to a larger image. I suggest
doing it this way. If you have your image width set to 200 in the admin section
make your images 300 to 400 wide (item_number.?) this will hold the page look consistant
on the details page and give you a larger clickable image.

Sell Similar Function
If you have several items that are very similar you can reuse the item to create a new item.
In the Admin pannel, Search for the item you want to re-create as new. On the search results
page there will be a list of items and a link to Sell Similar. Click on the link to add the 
new item.
