This site runs on the Everything engine, which, AFAIK, you can download and play with all you want.

I have to concur with the earlier posts that recommended Template Toolkit and CGI::Application, two excellent modules, IMO.

I'm not sure what your Perl knowledge base is like, so I'll also mention that the DBI is where you want to look for talking to the database. There's a ton of tutorials out there for it, including here in the monastery.

Have fun!
