Any rules ideas that I post for BT aren't official unless an up to date BT rulesbook declares otherwise. You might have to wait at least a fortnight for me to reply because I'm usually very active. I won't discuss real life politics or religion on any of these forum(s), but my favorite color is yellow like my skin color (hint).
