Vertaling van moderator

Many websites prohibit misleading usernames that imply an official role on the website such as "admin," "administrator," "webmaster," "system operator," "sysop," or "moderator."

So why not just say "If you think you've done enough for Tatoeba to become a trusted_user, write a message to a trusted_user or moderator that speaks your languages and tell them. They will look over your work to check whether you've understood the system or not. If you have, you're in."?
