Allegro Melody now has a Facebook page. It doesn't yet seem to be coming up in a search, as it was just posted yesterday, but check back and it should be there soon! Or just send me your email or Facebook name and I'll send you a friend invitation.
I also added an Allegro Melody artist page:
You can sign up here to be a "fan" and receive notices when I update.
I imagine that the "Friend" page is more personal, with more posts; the "Artist" page will be updated only with new images or events.
I'm still figuring out this Facebook thing - I'm sure it will morph as it makes more sense.
