BuddyPress.org

For a site I am building, I need to do two things to the user roles in groups, and was wondering how to achieve this? Or at least where to go looking for answers.

1. Firstly, to add another user role, more or less at the same level as the normal Member one.
2. Rename all of them. (This I am guessing can be achieved by monkeying with the language stuff)

Any help would be greatly appreciated.
