Re: Starting an all-women's class
of course I can't speak to their specific situation but I know that dojo pretty well. I've trained there a good amount of time over the years. I believe I even trained with Jennifer at a recent seminar in MD. My impression of some of the senior male aikidoka in that dojo is they are an energetic bunch not necessarily 'rough' as a group. But of course, I'm not there regularly.
My advice would be to anyone who feels like a club is not addressing their needs...open your own and create the type of environment you seek. You may find a whole new set of challenges await.
