A member becomes trusted when we reach a point where we think they are ready.
- User has been active for a while, demonstrating a commitment to editing here.
- Submissions are complete and accurate, and don't require any fixing up by staff.
- User communicates well, in terms of being able to actively explain their edits and resolve disagreements with other editors.
For #3, you don't have to be fluent in English. There is one user who's submissions are always correct, but he doesn't reply to any PMs from staff, nor does he post, so we aren't going to promote him to trusted.
There are some users who should probably be trusted, but who aren't simply because they aren't frequent submitters, or more likely haven't been noticed. In your case, the main problem is the lack of track credits, and the fact that your account is restricted from new album submissions. I'd be willing to try removing your restrictions to see how you do, but trusted is going to take some patience.
