bbzswa777, it's interesting that playing melodies rather than "campfire chords" was more interesting to you. Back when I was first learning, I had the opposite experience. I was learning melodies and stuff for about a year and I was bored to tears. A friend of mine showed me a few chords and some cool songs that used them...and I was off an running!! Just goes to show how everybody is different!
Tracy, I'm not a singer, but I know it can be hard to do 2 things at once, which is what you are doing when you play and sing at the same time. If you look through these forums, you'll find plenty of people that run into the same problem. You need to get to where one of the things you are doing is totally automatic to the point that you don't have to think about it.
