I know, many people call right off the bat, and I've seen the other threads with this advice and just didn't follow it. Bad Fribble.
About five years ago I registered a .net that I liked because the .com was taken. I built a site up on it and now that site earns me a good six figures a year, but I've always regretted going with the .net because I would see the .com sitting there, covered with ads, no content, occasionally a virus, doing nothing but skimming the traffic I built and hurting my brand. I had sent no less than a dozen emails to the registrant's email address, and never had a response.
For some reason, two days ago I just picked up the phone and called the number listed in the whois (duh), actually got the guy on the phone, and it turns out that he had no idea that I had established the .net and was assuming the type-in's were just dumb luck. Suffice it to say I paid quite a bit less than I expected to for the domain and am stoked to get rid of the garbage on the .com and just forward it to the .net
The moral of the story? Just call!
