If you're interested in teaching women's self defense AWSDA is an excellent resource. They have a good referral database and host a superb seminar every summer in the US. Whenever we've gone we've found holes in parts of our teaching where we didn't even know there were parts Legal aspects self defense, awareness drills, how to teach basic groundwork in a few hours, inspirational talks by authors and activists, how to deal with the police (by cops), teaching rape survivors and so on all get covered. I'm not a paid shill, just a member who's found it to be an excellent investment in time and money.
