Learning Guitar

This morning I had my first ever guitar lesson. I've been trying to teach myself using the internet, by using videos online and using some books that I found in a charity shop, but I've reached a point now where I think I would probably learn more by having a teacher. This lesson was a group lesson and I met lots of new people. It was a mixed age group, but I have a feeling that I was probably the oldest one there. We were shown three different chords and I need to make sure that I practice them, ready for our next lesson, as we're going to try and learn a song using those three chords.
