i think the basic concept is that EM is a specific PRODUCT, whereas SBO's are what makes that product work and SBO's occur in many other products that may, or may not, be just as good as EM. afterall, SBO's are a bigger issue than EM.
i am not against it, but an SBO forum has a very specific focus that might get lost if that occured. as i am learning, SBO's and your average strain of probiotic are two different animals.
