Here is an option for folks who don't have CGI access:
http://www.cgispy.com/scripts/auction.shtml
They offer free hosting of their version of the EveryAuction script. It doesn't have all of the same features as the one I wrote, but it will work, as long as you don't mind their banner ad on your auction page. You also won't be able to change the style, etc. to match your forum, like you can with the version I wrote, but it will still be an auction.
To use this simply change the URL in the iframe area of the template to match the auction that is hosted at cgispy.com. Then there is no need to worry about uploading the files, CHMOD'ing, etc., yet you can still integrate the auction in to your site. This is obviously much less desirable than keeping the script on your own server, but as a last resort for people who want to use this script, but don't have a server that allows them to use PERL executable scripts, I thought it was a good option.
EDIT: I also just found this page:
http://www.planetscream.com/auction/
simply click on "new page" to start creating your auction site.
There are many other sites that offer free EveryAuction hosting... just search google for "free EveryAuction hosting" and you will find a few more.
Hope this helps
NOTE: I do not have any experience with any of these free hosts, nor do I endorse any links in this post. Just trying to help.
