Carl,
I'm not sure if you have this included or not, but does the BRD include Canadian rules differences? If not, do you think it would be possible to add them? There are a number of them, and it would be a nice addition for those of us north of the border.
Here's a link to the Baseball Canada webpage that has a list of the different Canadian rules:

What do you think?
