Have you recieved an email from IDSG, attempting to have you register your domain name in other TLD's? This is a scam, first reported by the FTC several years ago, and surfacing once again.
Do not respond to their email.
"Necessity is the mother of invention" is a silly proverb. "Necessity
is the mother of futile dodges" is much nearer the truth.
