So that means, since my name isn't on the list, I can't upload anything by way of YSI?

have you sent a pm to LLOS asking to be put on the list? If you can only upload with YSI or have a paid account there you can be on the list.

but yes, it is correct that only the people on the list can use YSI to upload videos.
