Incoming FTP directory config

I guess this task is quite usual, however, I've never done this before, and had to do some googling to make it work as I wanted.

Requirements:

• user public should be able to create new files and subdirs under /home/joe/incoming/
• only joe and nobody else should be able to read the contents of, rename and delete from /home/joe/incoming

After some finetuning, the addition to proftpd.conf is the following:

<Directory /home/joe/incoming>
 Umask   002     002
  <Limit STOR CWD MKD XMKD>
   AllowAll
  </Limit>
  <Limit READ RMD XRMD DELE SITE_CHMOD RNFR RNTO>
   AllowUser joe
   DenyAll
  </Limit>
</Directory>

Also, user joe is in the same group as user public.

Quite a boring post, I admit, but I want to save some time next time I have to do it.
