softcore

I was just getting ready to register a domain name for a new pay site out of Vegas and I didn't want to register a trademarked word again, as many of you had subjected is not good, as I did with "playmate"... It looks as if Microsoft "xbox" has a trademark for the letter "X" does this mean we are all fucked if we use the letters X, XX or XXX In our domain name, as I was by using "playmates". Any opinions on this????

thanks for you opinions..
