I agree tabberone has a great site! I'm not sure that we have the cajones to actually file suit against Cartier, but we definitely plan to heed much of her advice.
She needs to do a bit of site maintenance, though, as I've found a bad link or two there like this one:
http://tabberone.com/Trademarks/folder/TrademarkInfringement.html
That one would come in handy, too
