Stan, I ran across your old post and thought I would follow up with
this in case you still had questions.
If you go to http://www.uspto.gov/main/trademarks.htm,
they will be
able to help you. As far as the website being active for two years...Is
that your website or does a duel registration exist? Anyway, if there
is an owner****p problem, http://www.domainnamedisputelawyers.com/
may
be able to answer your legal questions for free.
Hope this can help you some...
Take Care,
