How to get Apache to write files as group writable?

[Jay Paulson]

Yet another file permissions question! :)

I have my file permissions set up so that each local user who is in the 
same group when they create a file it becomes group writable.  However, 
even after I add apache into the same group that the local users are in 
(in this case the www group) and upload a file through a browser it 
doesn't make the file group writable.  How do I configure FC3 to make 
apache write files to the file system that are group writable (664)?

Thanks,
