Brand new to the website; should be informative. I think in the first diagram for the C7 major chord the high E string should be shown as “play open” – not muted.

Hi Alan, thanks.
Do you mean C7 (dominant) here …

If so, the open E is optional. I personally think of that chord shape as moveable so would rarely play the open E, but it’s certainly in the chord so you are right about that.
There is a problem though with that image which I will fix later tonight or tomorrow, it shows the correct fret number but on the wrong fret.
