To answer Sunny's question - if you go to the upper left corner of the page and click on "guitar chords" and then go to the boxes on the right under the fretboard and choose a chord it will show you where your fingers go - - for example if you go to the first box and choose E and then go to the second box and choose 7 - then right below the boxes is a button marked "get". Press it and it will show you the E7 chord on the fretboard. Looks like there's a lot of other things to choose from up there - you just gotta play with it a little
