heh, if I were you guys I'd keep a LONG way from anything that involves PERL and flatfile databases.
In my experiance the best combination is PHP4 and MySQL. If you want somewhere to host this check out (url="http://"http://www.phphosting.com/")http://www.phphosting.com/(/url) and (url="http://"http://www.tera-byte.com/")http://www.tera-byte.com/(/url)
As for the language, PHP is very PERL like, except for one very important exception: it's an embeded HTML language. That means that it basically is placed in an HTML page, rather than being a seperate stand-alone program. It also benefits for faster execution and a more stable enviroment.
As for the scripts, there is vbulletin (http://www.vbulletin.com/) which is basically UBB for PHP/MySQL, w-agora (http://w-agora.araxe.fr/) which can do just about everything imaginable, from discussion to news to file transfer and phorm (http://www.phorum.org/) which is the discussion board I use at (url="http://"http://www.evp.f2s.com/boards/")http://www.evp.f2s.com/boards/(/url) There is also a in-progress script at (url="http://"http://sithweb.sourceforge.net/")http://sithweb.sourceforge.net/(/url) which aims to power such sites. It's written by me, and it is on a tempory development hault while I concentrate on my 6th form qualifications at school (bleh)
