What is a NameError?

Hi,

What is a NameError?  When I visit the root page of my application, I
get an application error.  Upon checking the logs, the stack trace is
below.  I have also included my environment.rb and routes.rb files, if
that''s helpful.  Any direction you can point me in is most
appreciated.

NameError means ''I couldn''t find that''. do you have a
file
user_observer.rb defining a UserObserver class ?
