Your post sounds like "Hi, I'm new here -- and by the way, your site looks like crap, and you've written the code wrong." Also, I'm curious to know how can you tell that MVC and Templates aren't being used on the site already.
Anyway, you've got folks attention .. as has been pointed out, you can specify your own CSS to change the way the site looks, and if you're interested in working on the site code, you can contact the pmdev group about that. However, my understanding is that it takes a while to get into that group, and you have to first demonstrate that you have some Perl chops.
This is a close-knit community -- so don't expect to fly in and immediately start changing the site. Some of us have been here a while, and like the site just the way it is. It's not gorgeous or flashy, but it's most useful, as well as being an excellent little corner of the Internet.
