Funny thing i discovered recently, when you tried to register a domain that contains "godaddy" within the dn specified, it shows a message and not allowing you to register their trademarks!? :upset:
I think it would be wiser to go with a more generic (brand-neutral) name.
BTW Enom has already confiscated names that merely contain the string 'enom'... you definitely don't want to register a godaddy TM at godaddy
