Whoops I wasn't clear on what I was trying to say. I do plan on running a website on this domain. Do you now recommend me to register the trademark? The domain is nice enough to where I think It would be good to have this sort of protection.
In the U.S., it's all about "first use" rights, of the mark and evidence, to prove first use...Not necessarily, "first registration" of Trademark.
As for a level of protection, without registration, the TM & SM symbols are used with unregistered marks, to give notice to the world of the rights, to which you are claiming: TM for trademarks, or marks that represent goods, and SM for service marks, or marks that represent services.
The federal registration symbol, or ®, is reserved for marks registered in the U.S. Patent and Trademark Office (
https://www.uspto.gov/), which is total protection.
