Thanks for this great code Mike. I have decided to try and implement this
for the site.

I put this usertag in catalog.cfg. I am not that good with perl, but I think
I understand what is going on here. However
-----------------------
{SERVER_NAME} -> {www.imagemogul.com}

{DOCROOT} -> {downloads}--   I take it I should make a folder called like
"downloads" that is in my www directory

{tmp_download} -- Is this a folder called tmp_download, that will be created
on the fly, inside of {downloads}
-----------------------

Then in mail_reciept I have:

[row 82]
[column width=80 wrap=1]
Download here: [enable-download resource="/path/to/downloads/[item-field
download]"]
[/column]
[/row]

To what extent should the path/to/downloads be filled in? I have tried it
already but [enable-download resource="/path/to/downloads/[item-field
download]"] doesn't become a link, it just prints to screen.

I am trying this in catalog.cfg, because I am currently in a shared
enviroment, and don't have access to VENDROOT/usertag/. However I am in the
process of having a dedicated server setup for me, so if this won't work, I
will try it there when it is done.

Thanks again guys
