Found this site about a week after I started paying for 1on 1 teaching.
I love my class but having Fiddlerman.com available 24/7 is an absolute bonus.
Great tutorials, loads of free arrangement downloads, some play along duets and a really good forum with loads of support from other people with varying degrees of experience.
All in all, for a free site, with instant feedback on any learning issues, the option of Skype 1 on 1 tutorials and a shop with great deals on equipment which is far cheaper even with shipping costs to the UK to any other shop I have found, there is nothing comparable out there.
Well done Pierre Holstein for putting it all together.
