Ok, so using the "Find a Geocacher" function I've gone through the "0's" and the "Z's" and I cannot find anyone with those characters east of the Mississippi.
-edit- As an experiment I tried entering the number 1 (I have found a cache by 1hotmom so I wanted to see if it returned her in the search). It did not return her in my search so apparently using that feature on geocaching.com is not reliable as a search source for this cache. So now what? Does anyone know of a better way of searching out cachers with the alphanumeric requirements?
-also edit- WVHunter, what if there are multiple names of cachers who've hidden the cache. For example - "CLCombat and Aquacache"? Can you count either one or only the first one?
-also also edit- I can only handle the stress consumption of one challenge at a time. Now I've got the Fizzy and the Alphanumeric to deal with? So help me if you create another one soon I'm gonna explode.

-the person who authors these edits has just been sacked- How about one "the" wildcard? Allowing us to use one geocacher's name that starts with "the" (i.e., The 8astard).
If you smacked a kid in the face with a bottle of Johnson's No More Tears, would it create beautiful irony?
