So I'm reading this book "The Everything Wedding Book" revised and expanded second edition. by Janet Anastasio.... and a bunch of other people, anyway.
There is a section on it that states HUD (Department of Housing and Urban Development) has announced a bridal registry initiative in which an engaged couple can open an interest-bearing saving account at any one of thirty FHA-approved lenders around the country. Your family or friends can contribute toward a down payment."
Then it talks about how it "etiquette ladies may shudder but this is becoming an acceptable way to ask for a money gift. .... It might be tacky but better than receiving unwanted crystal stemware."
I also found this.

This sounds awesome right now! I wish I could set something up and just post a link to it on my wedding website.
