Have a look at the current "Tunes Wanted" threads for more on posting midis; they should usually be sent to Alan of Australia for the Mudcat Midi Site (link under "Quick Links" on the main Forum page) -abc format and miditext can go straight into threads; RA isn't possible at present.  Look at  Mudcat FAQ - Newcomer's Guide  for (much) more info.  For more folk music resources, look at the Mudcat Links page (top of the main page) and then just go exploring!
