I've been using this online training for long time already. I would say it's not only for beginners but also for intermediate levels too. It covers many different guitar styles.
During this long time I've seen how the page positively evolved and I'm happy to see how one person (justin) which is doing a superb job in giving those lessons for free is getting more and more attention. This is in my opinion a good example of how perseverance, free content and love for what you do can at then end pay back with a very good reputation from users and I guess good money with the selling of same free online content but as DVDs,books, etc
