I debated with this too...After reading many of the threads on this topic, I decided to register. I am not advertising it, but when people ask, I am able to tell them. Not everyone you invite will be abe to attend, but they may still want to send a gift. Better to get something you want, then something random. Bed, Bath, and Beyond is a great place to register, b/c they always send out 20% off coupons.
Also, someone will probably want to throw you a shower. It is just easier to be registered. I did not do a big registry, (no china) but it is there.
