Thanks for the suggestions guys. Ezfolk is good, but is specifically for a special type of harmonica called the Melody Maker. However, having read about it on the site, I'm very tempted; after all, I don't want to be a virtuoso, just do a bit of accompanying. Harptabs is also good. Many thanks; but more suggestions appreciated.
by the way, I'm not looking for a freebie, but something good like Jamplay. Harmonicalessons.com looks quite good. Anyone heard of it?
