I'm doing exactly the same. Once in a week I take lessons by a "real" instructor, but beside practicing what I learned in these lessons, I decided to join GuitarTricks.com. It gives me the perfect chance to recall what I've learned (or maybe better: what I've should have learned...), but it also gives me the chance to see some new stuff and to repeat as much as I like.
Hope this helps me to become better!
