Question on File Permissions

[Debian User <debuser@airgazm.com>]

I set up a Web Server here on my Debian Box.

Question, is there any way to set a default file permission on a certain 
user folder inside the /var/www/ folder.

I want to setup accounts for users to upload web files, but the problem 
is that whenever I upload files, the files always default to read only 
and I have to run the chmod command each time, instead of them just 
defaulting to read and exe access for all.  

Is there any way to set this.

Thanks in advance.
