Forums (new school) and Message Boards (old school) are among the most interactive of all memberships. Forums are traffic magnets and they exist in literally thousands of niches, test me on this and you will find one in every niche that comes to mind.
Forums are membership sites that are designed to serve large groups of people who share a common interest and contribute to topics and comment on the topics of others known as threads. Threads are simply topics that members offer commentary, offer feedback and recommend resources through an evolving conversation.
There are many reasons why you should participate in a few quality forums including; mastermind with successful online marketers, benefit from the experiences of fellow marketers, identify joint venture partners, share your ideas and much more.
