The kind people at InstantASP donated their forum and knowledge base products to the book club for our use. From initial use of the product, I have to give them two thumbs up! They are easy to work with, inexpensive, and very performant. If you are a current user or plan to sign up with this book club, your email address and password is your login credentials for the forums system. Stay tune for more on the knowledge base tool and our usage of it.
