Mea Culpa! At least minima culpa.

DigiTrad hasn't been updated for a couple of years, due to an astounding number of distractions (like earning a living and trying to get CAMSCO Music operating properly), a couple of major computer crashes and a fierce headache.
The new version (9500 odd songs) is now undergoing conversion to the various versioms that have become necessary--DOS, Windows (several editions), Mac (several editions) and the awkward (but fast) HTML version here on the Internet. Since the convertor is also burdened with other things (He's the co-editor of the wonderful Loomis House edition of Child), I can't promise just when it will be released.
One advantage of the Mudcat is that songs posted on threads are available, even if not as conveniently as those in DigiTrad. We'll incorporate your contributions as soon as we can, but please try to be patient.
