reg fee, big time legal issue with it IMHO you could try to sell it to myspace for a few hundred buck
Yeah, myspace will most likely chase it down too, as they are an internet-based business. Get rid of this asap is my advice- you could maybe get something for it though- try ebay. Alternatively, develop a site on there quick, which is different to the myspace.com website. This will give you a better ground if a tm issue did arise, and would also improve the value of the name.
Unless you are wishing to dice with death i wouldn't even TRY to sell this domain. Microsoft will be especially touchy as it's their latest venture and most popular at that IMHO
