How do i delete a request that has been completed already? I don't want it to show under my profile.
You can't, once someone has submitted a translation it stays like that.
Nurya, why do you want to unlink a fulfilled request from your profile?
Hello, when I Google my self, it shows what I've requested to be translated for me. I need it to not show that. I want it to be private.
If "Nurya Berrones" is your real name or a well-known pseudonym, and you do not want it associated with the requests and translations, you could ask moderators to change you User Name. I believe there is a Help thread for that.
Google will still show old results for a while, until the rating of the page with the present name dwindles down due to disuse.
