I think that part of support is helping new people with these kinds of questions (just as you are doing here), and sometimes more experienced people with them. Questions like this won't hurt the support aspect of the forum, will they?
If someone is trying to spark debate, or has a history of debating on Miracle-Mineral-Supplement , then I agree that their posts should probably be moved to the debate forum. But for genuine questions, even though for which we do not have ready answers, don't we want to be able to discuss them here?
So, this may not be the popular thinking on this ... I will go with whatever the concensus is ... but I for one think that valid inquiry or questions belong here, unless the debate gets out of hand.
