Moved to Questions and Suggestions... and my personal bias would be against subforums, but instead reorganizing the stickies at the top. What if we had a few stickies about different ways of homeschooling, and I collected some threads about each... we couldn't cover every method, but we could cover unschooling in one sticky and have another sticky for other methods (because I don't think there are any other single methods with as many followers there). We could do same with some subjects - we have a Math one, but we could create a Reading and Writing one, anyway, since that comes up a lot.
I agree that homeschooling doesn't lend itself to neat distinctions as well as other areas... as an unschooler, for example, dividing threads by "subject" wouldn't be very relevant to me. I also see a lot of people who might not call themelves unschoolers, but in practice learn in pretty much the same way as we do... and there are some unschoolers with whom we'd have very little in common.
