I was on their Titus 2 forum for a time and have rather mixed feelings about their way of doing things. Their materials, in general, have some good advice, but OTOH, they tend to be quite legalistic, promoting a head covering, dresses only, stay-at-home mom, etc, program as being the only truly biblical way to live. The forum was strictly run and I don't know how many of my posts were disapproved because they didn't line up exactly with their standards. I think it would be interesting to see the Maxwells in person but would have my discernment meter set on "high". Oh, BTW, the book your wife read was "Homeschooling With a Meek and Quiet Spirit" - I never read it but heard it mentioned frequently.
