I love this website and the high-quality free instruction (and paid instruction) they offer. At all levels of ability, there's always more to learn -that's one of the things I really enjoy about the guitar.
As you get to the point where you feel confident and comfortable with the basics, you might want to consider teaching. There are students of all ages eager to learn how to form chords, strum, pick simple melodies/riffs, etc. Why not begin helping others learn?
I've placed a bunch of the templates, worksheets, theory lessons, etc. that I've used as a teacher online for free. If you're a guitar teacher, or interested in becoming one to make some extra cash, these free resources could make things a lot easier for you. Check it out: http://www.teachlearnguitar.com
And keep coming to guitartricks.com! Their lessons and resources are excellent. I even direct my students to this site to expand their learning experience.
hope this is interesting/helpful,
