Smashwords itself does not have a forum, but there is a forum called "Smashwords Forum" which you can sign up for. (Google it to get the address.) It has no affiliation with Smashwords, but was started by someone who thought there should be a forum on it. However, it has only recently got going, so the membership is still limited, so the number of replies you will get will also be. As far as Smashwords support: in their FAQs they are very clear on what they do and what they do not do, so it depends what your needs are. They don't edit your book, but they do give you clear indications in the style guide how to do so, and give you links for various independent editors, book cover designers, etc, if you want to pay for such services. Altogether Smashwords offers less than a paid service, but still quite a lot for free. And you have the assurance that Smashwords is not trying to rip you off. Direct support: I emailed them a question, and got an immediate and satisfactory reply.
