I'm afraid that option 1 is out of the question for me, seeing on how I compose on my school chromebook. But I checked, and Noteflight does support export to MusicXML files.  I don't know a good way to test the quality of it, seeing as most programs are blocked, but it can't be as bad as importing XML, seeing as that doesn't even work.  Now all that's left is to figure out what to arrange...  Thank you so much!

I'm an amateur composer, and I'd like to arrange for this site, but I don't want to spend a bunch of money on Finale to do it.  Am I allowed to submit an arrangement through .MID? I mainly compose through Noteflight, so odd notation shouldn't be an issue.
 Thanks!
