For various reasons related to our Emotion Code trademark, we ask if you're going to start a site about The Emotion Code or related to it that you not use "Emotion Code" in the domain name. Try using "EC" or "TEC" instead, or another variation. We're not lawyers, but very good ones tell us we have to do this to preserve our trademark. Also many users have told us they find it confusing.
If you already have a domain with "Emotion Code" in it, redirecting it to the "EC" equivalent is fine, just as long as the main one users see and you promote doesn't contain "Emotion Code."
"Emotion Code" in sub-domains is fine, like "emotioncode.example.com" - we're just concerned about top-level domains, the .com itself.
We've told this to anyone who has ever asked us, we just wanted to make it public so more people could be aware of this policy.
But I see other domains using Emotion Code in them!
If they're not TheEmotionCode.com, they're not allowed, and you should contact the owner with a pointer to this page.
