As an [almost] new Kontakt 2 owner/user (it arrives Monday or Tuesday, depending on the whims of UPS delivery in Hawaii), I saw this Forum here on NS and assumed that might be the only one. It's not. Native Instruments has a full support Forum on its site. I think the topics in the Kontakt section here mostly relate to the (currently) new Version and interactions with other products that are represented at other NS forum areas.
Drill down from "Community" to "User Forum" and you will find a long list of NI products with Kontakt's area having almost 4,000 threads.
