[How to set up my first multi-cache]

I too am trying to accomplish this task. And am fully aware of caching, its the actual setup that seems unclear on the Geocaching website. I'm looking for very clear instructions for editing the cache on the site to make sure it come out the way I want it be. I believe I have plenty of experience in caching and hiding them. It's just the editing thing that stumps me. Are there any other sites or books that explain this in detail like pictorials of different types of caches

[Challenges?]

Locating challenges on the Iphone application doesn't exist. In the search section there should

be a section under advanced search. Also searching for them by their code should be an option.

Is a challenge considered a geocache. If it is doing a search for a nearby challenge should show

up in the search along with it's own unique icon.
