[texhax] question

[Zbigniew Nitecki]

I was trying to write to find out if there is any mutual-help "chat" 
network on TeX, but perhaps you are the people I should be contacting.  
I occasionally come up with problems I can't figure out, and would like 
a resource to turn to for help.  (I am a member of TUG)
Here is my current problem.  I am trying to generate a short vita, 
using the attached files, of which shortvita.tex is the "master file".  
For lack of a better document class, I am using "letter" (is there a 
better one?) and am apparently running into some silly problem with 
this class, but I cannot find any documentation on the letter 
documentclass---in the Latex Companion or other latex manuals I have 
access to.  Is the problem obvious to you?
Here is my error message:

and the relevant files are attached.
