Unix copy to different groups help request

[Jungle Boogie]

Hello Friends,

This just in: computers always do what you tell them to do!

Now you great people: please teach me so I can tell my computer what I'm 
trying to do.

Objective: cp file to /usr/local/www/data for lighttpd without using sudo all 
the time.

Problem: It seems like I have the right group everywhere: file, /usr/local 
/usr/local/www and I'm in that group, too.
