I belong to a Yoga Lovers forum on SparkPeople.com (free diet website) and one of the members posted about a Global Mala during the equinox.
Basically you would plan 108 asanas or something like that the weekend of Sept 21 thru 23. If your interested in your studio participating, you can go to http://www.globalmala.org/ for more information and to sign up. In addition to being a pretty cool idea, it may bring new people to the studios...
Of course, if you really want to make my day, you'd do it on the 23rd as I'm out of town until then. But even if I can't go, I thought I'd let you know about it...
Namaste.
