OH... Yes, of course you have my permission to translate "Since you Insist..." into Hungarian. My only request is that you send me the link to your translation, once it is out, which you've already offered. ;)

I do keep an updated list of authorized translations of my work, which you can find here, in case you want to see it. Your name has already been added to it.

Thanks so much for gifting me with the honor of dedicating some of your precious time to translate a work of mine. I appreciate it more than words can say.

Good luck with your project.
Sincerely

pekeleke
