Nasruddin is a very private person
He will respect your privacy completely. He collects information about you on this website, if you provide it, and will not sell, share, or provide that information to anyone else without your permission. He probably won't even ask for your permission, because he doesn't want to share your information!
On the other hand, you may tell anyone you want about Nasruddin and his website, and say as much as you like about him and his work without asking him at all.
In fact, if you have a website, you are encouraged to link to Nasruddin's site. He would be very pleased.
