@crculver, good to see someone willing to help !
Peter is the man for your request, try send him a BW message, he always answer.
In the meanwhile , you will find everything you need on: http://www.bevolunteer.org/trac ;
BW Framework is rox, it is based on PT. I think it is not that bad, but true, it is not Zend or CakePHP.
Be happy not be compelled anymore in using what people call Old BW which was even more specific (It was the first version I made in a rush in end 2006, not even a MVC).
Probably in some time (2/3years ?) we will start a move to something more powerful, living BW Rox, but, they are currently no plan to change it, since we have not yet found a dead end with this current system (except that you are to invest a bit of energy in understandting how it works, but is is very classical in fact).
I strongly suggess that you setup a local environment, choose an easy ticket and propose a fix. If so I am sure that the DEV Team will pay attention.
If you need some help, feel free to conatct me, I usually answer in less than 24h00
