You may think you have the experience that everyone wants, but what really matters is how others ultimately perceive you. What's important is that you know your subject and present yourself professionally. Martin and Whalen say you should plan to put in at least two to three years of work to become an expert. They say taking advantage of media is key. They also agree that discussion lists are a great tool for establishing yourself and learning more about your field.
Discussion lists are a form of e-zine .
There are two types of lists, moderated and unmoderated. Moderated lists are screened by topic experts and they generally contain higher-quality content. This familiarizes you with the level of discussion and the list's participants. Once you're established, begin offering solutions and post every other month. Limit your involvement to three or four lists so you can manage your communications.
