Thanks for your compliments. I think you are absolutely right to file it under Franck and not under Cortot, because it is basically the piano part of the Franck violin sonata with most of the violin line reworked into the texture. But it is definitely more Franck than Cortot. =)
As for the Les Mis, it is my own transcription, but it is basically One Day More with my own coda that draws on a couple other themes from the musical (this started out as the finale to a whole Les Mis fantasy that I'm still not completely happy with and is too long and difficult and that I plan to revise). I'll leave it to your discretion how to file it. If you choose not to put it up at all, that's fine too, because I wouldn't want your site to get in trouble with copyright.
With my compositions, I think it would probably be best to create categories for piano and duo? I'll upload a couple of my other compositions later for your consideration. And actually, can you hold off on the rag? I have an alternative recording (not live) of the rag that you might possibly prefer.
EDIT: I forgot to mention that you can find the Franck--Cortot score at http://www.piano.ru/scores/frank/fr-son.pdf
if you're looking for it. Cortot's name doesn't appear on the score but the transcription is definitely by him.
