[Iosonoilprologo]

I would like to register one of my compositions with the Library of Congress Copyright Office. When I went to their Web Page, I noticed that they list several ways to register your composition, but none of them showed the .not ending. I figured that after I finished the composition I would then have to save it in another type of file format. Have any of you ladies and gentlemen registered your work with LOC and if so, how did you go about changing the format to one that they would accept? The main reason I'm asking is because they say that sending the document through snail mail, may even take over a year before you get the registration certificate.
