It is a problem that I upload some arrangements with my students?
They work hard for music and for this site, they are accumulating transcriptions which is important for their self-esteem to be uploaded to this site, so they can work on other scores continuously.
This wouldn't be a problem if they uploaded their scores by themselves, but from the way I understand it, your country's laws would not permit this.
You need to keep in mind that the staff that processes the arrangements works just as hard as your students, if not harder. I'd venture to say you're demanding more effort out of people like Latios when you ask them to find proper titles for songs that you don't know the context of. Why should it be their job? The issue isn't that this music is exceptionally obscure, it's the fact that you cherry-pick these tracks from Zophar's Domain
because they're obscure. Why is that? Can you not rely on your students' integrity? Please explain this.
The motivation behind these sheets is certainly unconventional, but if I had any say in it, I'd decide that if you want to call these "joint arrangements", you need to put more effort into finding where these songs originate from. For the very last time,
this is not NSM's job, and to assume otherwise is taking advantage of a volunteer-based staff.
Aside from this, I have no issue with you submitting up to four sheets at once, as long as they're your pupils'.
