How do you change your registrant name with all registras?
 

I've been getting prank phone calls and I think its coming from a weird surfer, so I made my domains private, but some places like netsol and register.com are still listing my first and last name when I do a whois lookup.

Is there a way to get everyone out there to change it or do I have to make individual requests to all of these companies?

I'm kind of spooked by this.

back when i was running my own amateur site I got real letters from a guy in jail. Freaked me out big time so I can understand why you are worried.
