Check in with Eastern Michigan University's Autism Collaborative Clinic. They're outstanding and will be able to get you hooked up. Good luck!

Not sure what is available in your area, but online I like wrongplanet.net

Have you checked out MeetUp.com? This site is how I found some local support and there are all sorts of interest groups offered. If you don't find something in your area you can start a group of your own and may be able to help others that may be looking as well! Good luck! :-)
