I thought it was pretty common; in Britain they are often called "wedding lists", my daughter had hers at Debenhams and that was in 1995 and I don't recall it being unusual.
Same here! We, and several of our friends, have about 5 weddings to go to this year, and with the economy the way is is we thought it would be a little presumptuous. But I think most people in the UK have lists now, and we have already had confused comments by not having one.
My experience getting married here in the UK - nearly five years ago (has it really been that long?!) was that people
did assume us to have registered somewhere. Initially, we weren't going to register at all, but most of the people who were going to be attending, and even some who weren't going to be present (mostly on DH's side, but some from the US as well) persisted in asking us where we were registered or going to be registered, that we ended up doing so (with Debenhams). At least from our guests, it seemed to be something the guests appreciated having - a registry to go to & buy from, taking out the guesswork & hassle of gift selection - and not something they saw as presumptuous at all. We didn't pick extravagant & expensive things, however, just the everyday stuff we needed (everyday dishes, kitchenware, bed linen, etc). Steve had been living the bachelor life before (two place settings of cutlery, two or three pots & pans, you get the idea
) and I didn't move my whole household over here - just clothes & keepsakes. So we needed household stuff!
