Custom Commands: Gene6 FTP Server

Has anyone created or know of a pack of custom commands for Gene6 FTP Server?

If no such animal exists, I'm willing to create my own. I've searched in the knowledge base and through the forums though, and I was hoping for a little better help documentation. I've had a few problems with the custom commands I've created so far--pasted below for reference.

One command per line. Seperate it with "Enter".

Variables

%d working directory
%ft time of selected file/directory  
%fs size of selected file
%fo owner of selected file/directory
%fg group of selected file/directory
%ff  selected file(s)
%fd selected directory
%fa selected file(s)/directories
%lf local file
%ld local directory
%lt local file time
%ls local file size
%a input dialog

<type>
none text input field
n number input field
p password input field
%u login username
%p login password
%t local time
output: YYYYMMDDHHMMSS
%t<fmt> local time with format string
%ta prompt for time

%ta<fmt> prompt for time with format string

For example, I'd like to create a custom command for SITE PSWD, and I'd like to avoid clear text. Can anyone point me to something more descriptive?

Just press Edit Custom Commands and watch how the rest of the commands are built.
