If you're interested, I've got an Open Source web project that combines the concept of a forum with a blogging platform. It's called Sylbi, and more information is at

http://sylbi.arbingersys.com

It uses CGI::Application and is a true MVC application with a MySQL backend. I've tested it to run under Win/IIS and Apache, and installation is really pretty easy. The basic functionality is there, but there is plenty of work to be done. I have been busy with other projects, and frankly, I've been neglecting it a little.
