I got this email today. I want to see what you guys think:
"I left you a message yesterday by phone after discovering your registration of ionoffice.com. We have owned the domain for years, and were perplexed how you were able to register it. We are the definitive trademark and domain owner of ion on the Internet and ask you simply transfer it back to us. We can only guess what your intended use of it
would be, however, we will protect our rights. I can understand if you may not have been aware of our company, and we may be willing to discuss a future relationship, but you would be ill advised to use the domain or start a site with the term "ion" in it without our consent."
I guess he's claiming that he owns every domain name that includes the term "ion".
