My main area of expertise is the character of Admiral A. J. Chegwidden portrayed by actor John M. Jackson. I created and maintain "The Admiral Fact Book," which covers all information known about the Admiral so far from the show. However, I have watched JAG since the first episode and been involved in on-line JAG Fandom for several years and believe I can answer most general questions about the show.
I run the John M. Jackson Admiration Society, the unofficial fan club of actor John M. Jackson, and maintain its website. I also was involved in putting on the first ever JAG Convention and then went on to found the JAGFanFest - both west and east coast events. I have met almost all the actors as well as many of the writers, directors, and production staff. I occasionally write JAG fanfic, and I am the editor of The Jackson Journal, the on-line newsletter of the JMJAS.
