The forums have been an invaluable tool connecting people who have read the book and have contributed to discussions on biological topics and simulation models. Numenta.com has similar discussion forums on HTM theory and NuPIC. To reduce redundancy and to foster communication between the communities we have initiated a new forum on Numenta.com for discussions on On Intelligence. We encourage you to participate in the new forum. The forums on OnIntelligence.org will be available for perusal.
Users that do not already have an account on Numenta.com would have to register to post to the forum. Thanks for your continued cooperation and participation!
