It would be a great addition to the site to have someone teach how to read and write charts for guitar.

That's a great idea.

This tutorial is not explicitly about how to read a chart. But it does contain a basic chord chart & I use it to teach the whole tutorial. You can learn a great deal about reading a chart by watching it & referring to the chart image displayed below the video.
