Yes, the experienced boxes are red and the beginner boxes are grey but that is the only difference I can see! On my screens the Beginner lessons and the Experienced lessons for Blues, Rock and Country are identical.
I have literally accessed the site on my PC and iPad alongside each other and have verified that the above is indeed true. I can hardly credit that this is what I'm seeing!
I also can't find the "different lessons/courses at the bottom." that you alluded to. Where exactly are they?
There seems to be a problem here, either I am not seeing what you intend me to see on your website or something more worrying i.e. there really is no difference between the Beginner/Experienced sections.
I would very much like to find which of these options is right.
I'm hoping you get back to me on this.
