Forum marketing is an excellent form of advertising that basically consists of posting your thoughts and questions and getting responses in the form of replies. It is similar in some ways to writing an email from my point of view, except that what you write is open to many people. You are looking for responses to your posts in these forums. You are also reading posts that are written in response to somebody other than you, and you are able to gather different ideas and opinions about what works for people and what doesn't. As far as I'm concerned this is an excellent way to think through whatever you are attempting to do online.
