The easiest way to set-up a form of website for an online book club is to use of the many pre-existing social networking sites such as FaceBook, Yahoo Groups (http://groups.yahoo.com/) or Google Groups (http://groups.google.com/). They are free to use as they are supported by commercial advertisements. Just visit the sites and you’ll find that they are easy to use and a perfect fit for what you’re looking for.

I would recommend Proboards if you want to make a discussion forum. It’s free and easy to use.

For example, For the Love of Books is a proboard forum.—> http://fortheloveofbooks.proboards.com/
