Hello Babette,
All good questions, I tried to explain this on the goups description and above. The group is for Genos owners to meet in person, this is the only real difference. It is all good becoming a member of the forums and other online groups however I do believe it will be beneficial for local Yamaha Genos owners to be able to meet up sometimes. No one can deny the fact that the Genos is a very powerful and a complex musical instrument, and no one knows it all so we can all benefit from a helping hand or two, and it is better in person sometimes.
