If you (or anyone for that matter) have any doubts about whether something is appropriate or not for the forum, then send Sean a PM or click on the "contact us" link at the bottom of the page, and run it by him. Alternately, if your main interest is just keeping the commercial stuff out of the forums, then post the emulsion discussion in the forums, and advertise the commercial part in the Classifieds (if say, you wanted to do something like offer a discount on a product to participants in a workshop).
