I would tell them to kiss your butt.1st if they havent trademarked the name you have nothing to worry about.2nd If you have not done anything with with the domain you have not infringed on their trademark even if they do have one.3rd I sure wouldnt give them a darn thing and take a loss even if it is 8.88.4th I would let them know that you will be contacting your attorney and forwarding their emails to him.5th.If you decide you dont want to deal with all the problems I will buy the domain name from you for 8.88.. or whatever the registration fee was .
