Yahoo groups has a few great unschooling groups, and of course- My blog
which isn't entirely dedicated to unschooling, but I did link to the unschooling category. All the amazon books in my sidebar are for unschooling books and I'm still adding old things to the category from before I switched over to wordpress.
Anyways, we are eclectic unschoolers, because we do enjoy curriculum, but we don't have a lot of rules or requirements. Some unschoolers are really strict about the 'rules of unschooling" which IMHO is silly. My kids are happy healthy and free to speak up or speak out or make a new plan and they do all the time.
I highly recommend you check out that convention, though. It's absolutely HUGE and it's been going on for like 13 years now. It totally changed my life and I can't wait to go back this year.
