I'm new around here too. been lurking for a while... last week I read a thread about theory and it was a HUGE eye opener. I'm sorry I don't remember who posted this link (I searched and couldn't find the original thread), so kudos to whoever it was
http://www.zentao.com/guitar/theory/
he lays it out step by step in very simple fashion. I was even able to explain the circle of fifths to people who don't play music and they completely got it!
now I feel I have leaped a huge hurtle and I am so much more confidant in my knowledge. after all, knowledge is king!
