Craft Hackers is more than just a forum, however. Toni and her team maintain a blog exploring different aspects of crafting as a business and for added benefits and tips and tricks, you can sign up for a paid membership. I should probably at this point state that I have no affiliation with Craft Hackers except to think it, its creators, and the idea behind it are da bomb.
Even if you're not a crafter who is in the business of selling your work, I urge you to go join us on the forums there to make it a lovely lively place where crafters of all varieties can share ideas and projects. I'll be there as eliste as always. Also check out the chain-mail section cause some of those folks are seriously talented!
