Does anyone know any one that does group homeschooling? Or where I can go to find such info.
The thing you have to be careful about in 'group homeschooling' is that someone who opts to homeschool children besides their own CANNOT accept payment for doing so. Accepting payment is tantamount to opening an academy of your own, which makes you beholden to various laws and such that don't apply if you're homeschooling your own kids.
I don't know the particulars, sadly; I'm parroting back cautions that were given to me, so take what I say with a grain of salt. Do good research before launching into a group homeschooling situation, lest someone end up in trouble. :/
